²¹ So the Lord will make himself known to the Egyptians, and in that day they will acknowledge^(A) the Lord. They will worship^(B) with sacrifices and grain offerings; they will make vows to the Lord and keep them.^(C)

⁴ When you make a vow to God, do not delay to fulfill it.^(A) He has no pleasure in fools; fulfill your vow.^{(B) 5} It is better not to make a vow than to make one and not fulfill it.^{(C) 6} Do not let your mouth lead you into sin. And do not protest to the temple messenger, “My vow was a mistake.” Why should God be angry at what you say and destroy the work of your hands?
