18 And Jacob rose early in the morning, and took the stone that he had made his pillow, and set it up [for] a pillar, and poured oil on the top of it. 19 And he called the name of that place Beth-el; but the name of that city was Luz at the first. 20 And Jacob vowed a vow, saying, If God will be with me, and keep me on this road that I go, and will give me bread to eat, and a garment to put on, 21 and I come again to my father's house in peace—then shall Jehovah be my God. 22 And this stone, which I have set up [for] a pillar, shall be God's house; and of all that thou wilt give me I will without fail give the tenth to thee.

Commentary on Genesis 28:16-19

(Read Genesis 28:16-19)

God manifested himself and his favour, to Jacob, when he was asleep. The Spirit, like the wind, blows when and where it listeth, and God's grace, like the dew, tarrieth not for the sons of men. Jacob sought to improve the visit God had made him. Wherever we are, in the city or in the desert, in the house or in the field, in the shop or in the street, we may keep up our intercourse with Heaven, if it is not our own fault. But the more we see of God, the more cause we see for holy trembling before him.

Commentary on Genesis 28:20-22

(Read Genesis 28:20-22)

Jacob made a solemn vow on this occasion. In this observe, 1. Jacob's faith. He trusts that God will be with him, and will keep him; he depends upon it. 2. Jacob's moderation in his desires. He asks not for soft clothing and dainty meat. If God give us much, we are bound to be thankful, and to use it for him; if he gives us but little, we are bound to be content, and cheerfully to enjoy him in it. 3. Jacob's piety, and his regard to God, appear in what he desired, that God would be with him, and keep him. We need desire no more to make us easy and happy. Also his resolution is, to cleave to the Lord, as his God in covenant. When we receive more than common mercy from God, we should abound in gratitude to him. The tenth is a fit proportion to be devoted to God, and employed for him; though it may be more or less, as God prospers us, 1 Corinthians 16:2. Let us then remember our Bethels, how we stand engaged by solemn vows to yield ourselves to the Lord, to take him for our God, and to devote all we have and are to his glory!
