Verse 22. - And (or then, the apodosis now commencing) this stone which I have set for a pillar (vide on ver. 18) shall be God's house - Bethel, meaning that he would afterwards erect there an altar for the celebration of Divine worship - a resolution which was subsequently carried out (vide Genesis 35:1, 15). "The pillar or cairn or cromlech of Bethel must have been looked upon by the Israelites, and may be still looked upon in thought by us, as the precursor of every "house of God" that has since arisen in the Jewish and Christian world - the temple, the cathedral, the church, the chapel; nay, more, of those secret places of worship that are marked by no natural beauty and seen by no human eye - the closet, the catacomb, the thoroughfare of the true worshipper (Stanley's 'Jewish Church,' lect. 3. p. 60). And of all that thou shalt give me I will surely give the tenth unto thee. Literally, giving I will give the tenth (cf. Genesis 14:20). The case of Jacob affords another proof that the practice of voluntary tithing was known and observed antecedent to the tune of Moses

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, 1Co 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!And this stone, which I have set for a pillar, shall be God's house,.... Building an altar of it with some others, and sacrificing to God on it; and wherever God is worshipped, that place is his house, be it what or where it will; and Jacob did as he promised to do, see Genesis 35:3,

and of all that thou shalt give me, I will surely give the tenth unto thee; for the support of his worship; for the maintenance of such that were employed in it; for the provision of sacrifice, and for the relief of the poor, or for any use or service in which God might be glorified: this was imitated by the Heathens in later times, who gave the tenth of their substance to their gods, Jupiter, Hercules, and others (w).
