Priest: The English word is derived from the Greek presbyter , signifying an "elder" (Heb. cohen). Origin. --The idea of a priesthood connects itself in all its forms, pure or corrupted, with the consciousness, more or less distinct of sin. Men feel that they have broken a law. The power above them is holier than they are, and they dare not approach it. They crave for the intervention of some one of whom they can think as likely to be more acceptable than themselves. He must offer up their prayers, thanksgivings, sacrifices. He becomes their representative in "things pertaining unto God." He may become also (though this does not always follow) the representative of God to man. The functions of the priest and prophet may exist in the same person. No trace of a hereditary or caste priesthood meets us in the worship of the patriarchal age. Once and once only does the word cohen meet us as belonging to a ritual earlier than the time of Abraham. Melchizedek is "the priest of the most high God." (Genesis 14:18) In the worship of the patriarchs themselves, the chief of the family, as such, acted as the priest. The office descended with the birthright, and might apparently he transferred with it. When established. --The priesthood was first established in the family of Aaron, and all the sons of Aaron were priests. They stood between the high priest on the one hand and the Levites on the other. [HIGH PRIEST; LEVITES] The ceremony of their consecration is described in HIGH PRIEST - 1986 (Exodus 29:1; Leviticus 8:1) ... Dress. --The dress which the priests wore during their ministrations consisted of linen drawers, with a close-fitting cassock, also of linen, white, but with a diamond or chess-board pattern on it. This came nearly to the feet, and was to be worn in its garment shape. Comp. (John 19:23) The white cassock was gathered round the body with a girdle of needle work, in which, as in the more gorgeous belt of the high priest, blue, purple and scarlet were intermingled with white, and worked in the form of flowers. (Exodus 28:39,40; 39:2; Ezekiel 44:17-19) Upon their heads the were to wear caps or bonnets in the form of a cup-shaped flower, also of fine linen. In all their acts of ministration they were to be bare footed. Duties . --The chief duties of the priests were to watch over the fire on the altar of burnt offering, and to keep it burning evermore both by day and night, (Leviticus 6:12; 2 Chronicles 13:11) to feed the golden lamp outside the vail with oil (Exodus 27:20,21; Leviticus 24:2) to offer the morning and evening sacrifices, each accompanied with a meet offering and a drink offering, at the door of the tabernacle. (Exodus 29:38-44) They were also to teach the children of Israel the statutes of the Lord. (Leviticus 10:11; 33:10; 2 Chronicles 15:3; Ezekiel 44:23,24) During the journeys in the wilderness it belonged to them to cover the ark and all the vessels of the sanctuary with a purple or scarlet cloth before the Levites might approach them. (Numbers 4:5-15) As the people started on each days march they were to blow "an alarm" with long silver trumpets. (Numbers 10:1-8) Other instruments of music might be used by the more highly-trained Levites and the schools of the prophets, but the trumpets belonged only to the priests, The presence of the priests on the held of battle, (1 Chronicles 12:23,27; 2 Chronicles 20:21,22) led, in the later periods of Jewish history, to the special appointment at such times of a war priest. Other functions were hinted at in Deuteronomy which might have given them greater influence as the educators and civilizers of the people. They were to act (whether individually or collectively does not distinctly appear) as a court of appeal in the more difficult controversies in criminal or civil cases. (17:8-13) It must remain doubtful however how far this order kept its ground during the storms and changes that followed, Functions such as these were clearly incompatible with the common activities of men. Provision for support . --This consisted --

1. Of one tenth of the tithes which the people paid to the Levites, i.e. one per cent on the whole produce of the country. (Numbers 18:26-28)
2. Of a special tithe every third year. (14:28; 26:12)
3. Of the redemption money, paid at the fixed rate of five shekels a head, for the first-born of man or beast. (Numbers 18:14-19)
4. Of the redemption money paid in like manner for men or things specially dedicated to the Lord. (Leviticus 27:5)
5. Of spoil, captives, cattle and the like, taken in war. (Numbers 31:25-47)
6. Of the shew-bread, the flesh of the burnt offerings, peace offerings, trespass offerings, (Leviticus 6:26,29; 7:6-10; Numbers 18:8-14) and in particular the heave-shoulder and the wave-breast. (Leviticus 10:12-15)
7. Of an undefined amount of the firstfruits of corn, wine and oil. (Exodus 23:19; Leviticus 2:14; 26:1-10)
8. On their settlement in Canaan the priestly families had thirteen cities assigned them, with "suburbs" or pasture-grounds for their flocks. (Joshua 21:13-19) These provisions were obviously intended to secure the religion of Israel against the dangers of a caste of pauper priests, needy and dependent, and unable to bear their witness to the true faith. They were, on the other hand as far as possible removed from the condition of a wealthy order. Coarses . --The priesthood was divided into four and twenty "courses" or orders, (1 Chronicles 24:1-19; 2 Chronicles 23:8; Luke 1:5) each of which was to serve in rotation for one week, while the further assignment of special services during the week was determined by lot. (Luke 1:9) Each course appears to have commenced its work on the Sabbath, the outgoing priests taking the morning sacrifice, and leaving that of the evening to their successors. (2 Chronicles 23:8) Numbers --If we may accept the numbers given by Jewish writers as at all trustworthy, the proportion of the priesthood population of Palestine during the last century of their existence as an order, must have been far greater than that of the clergy has ever been in any Christian nation. Over and above those that were scattered in the country and took their turn there were not fewer than 24,000 stationed permanently at Jerusalem,and 12,000 at Jericho. It was almost inevitable that the great mass of the order, under such circumstances, should sink in character and reputation. The reigns of the two kings David and Solomon were the culminating period of the glory of the Jewish priesthood. It will be interesting to bring together the few facts that indicate the position of the priests in the New Testament period of their history. The number scattered throughout Palestine was, as has been stated, very large. Of these the greater number were poor and ignorant. The priestly order, like the nation, was divided between contending sects. In the scenes of the last tragedy of Jewish history the order passes away without honor, "dying as a fool dieth." The high priesthood is given to the lowest and vilest of the adherents of the frenzied Zealots. Other priests appear as deserting to the enemy. The destruction of Jerusalem deprived the order at one blow of all but an honorary distinction.
