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!

Ge 28:20-22. Jacob's Vow.

20. Jacob vowed a vow—His words are not to be considered as implying a doubt, far less as stating the condition or terms on which he would dedicate himself to God. Let "if" be changed into "since," and the language will appear a proper expression of Jacob's faith—an evidence of his having truly embraced the promise. How edifying often to meditate on Jacob at Beth-el.
