14 Three times thou shalt keep a feast unto me in the year. 15 The feast of unleavened bread shalt thou keep: seven days thou shalt eat unleavened bread, as I commanded thee, at the time appointed in the month Abib (for in it thou camest out from Egypt); and none shall appear before me empty: 16 and the feast of harvest, the first-fruits of thy labors, which thou sowest in the field: and the feast of ingathering, at the end of the year, when thou gatherest in thy labors out of the field. 17 Three times in the year all thy males shall appear before the Lord Jehovah.
Matthew Henry's Commentary on Exodus 23:14-17
Commentary on Exodus 23:10-19
(Read Exodus 23:10-19)
Every seventh year the land was to rest. They must not plough or sow it; what the earth produced of itself, should be eaten, and not laid up. This law seems to have been intended to teach dependence on Providence, and God's faithfulness in sending the larger increase while they kept his appointments. It was also typical of the heavenly rest, when all earthly labours, cares, and interests shall cease for ever. All respect to the gods of the heathen is strictly forbidden. Since idolatry was a sin to which the Israelites leaned, they must blot out the remembrance of the gods of the heathen. Solemn religious attendance on God, in the place which he should choose, is strictly required. They must come together before the Lord. What a good Master do we serve, who has made it our duty to rejoice before him! Let us devote with pleasure to the service of God that portion of our time which he requires, and count his sabbaths and ordinances to be a feast unto our souls. They were not to come empty-handed; so now, we must not come to worship God empty-hearted; our souls must be filled with holy desires toward him, and dedications of ourselves to him; for with such sacrifices God is well pleased.
