What does Genesis 28:20 mean?
After commemorating the holiness of the place where the Lord visited him in a dream (Genesis 28:12–13), Jacob now acknowledges the content of what the Lord said to him. He does this in the form of a conditional vow, declaring that if the Lord will do these things, Jacob will respond with actions of his own.Jacob's vow should be seen not as a testing of the Lord so much as a prayer of faith. Jacob seems to be saying that since the Lord can do these things, and has said He will do these things, Jacob is willing to trust and obey. Specifically, Jacob mentions God being with him and keeping him safe. He also adds two things God did not say explicitly: providing for him bread and clothing. In the following verses, he will mention one more condition and then the commitments he is binding himself to fulfill for God.
