Genesis 28:20

And Jacob vowed a vow ,.... Which is the first vow we read of in Scripture:

saying, if God will be with me ; the word if is not a sign of doubting, but is either an adverb of time, and may be rendered, "when God shall be with me" F20 אם "quum", Junius & Tremellius; so Ainsworth. ; or as a supposition, expressive of an inference or conclusion drawn, "seeing God will be with me" F21 Quandoquidem, Tigurine version. ; which he had the utmost reason to believe he would, since he had not only promised it, but had so lately granted him his presence in a very singular and remarkable manner, referring to the promise of God, Genesis 28:15 ,

and will keep me in this way that I go ; as he had said he would, and as hitherto he had, and for the future he had reason to believe he still would:

and will give me bread to eat, and raiment to put on ; which is included in that clause, "I will not leave thee", &c.; Genesis 28:15 , even not without food and raiment; which is all men can desire or use, and therefore with them should be content.
