And Jakob vowed a vow, saying, If the Word of the Lord will be my Helper, and will keep me from shedding innocent blood, and from strange worship, and from impure converse, in this way that I am going; and will give me bread to eat, and raiment to wear,
Jacob's Vow to Avoid Bloodshed, Idolatry, and Impurity
Targum Pseudo-Jonathan on Genesis 28:20
