[13] ISA 19:21 And the Lord shall be known to Egypt, and the Egyptians shall know the Lord in that day, and shall do sacrifice and oblation; yea, they shall vow a vow unto the Lord, and perform it.

ECC 5:4 When thou vowest a vow unto God, defer not to pay it; for he hath no pleasure in fools: pay that which thou hast vowed. 5 Better is it that thou shouldest not vow, than that thou shouldest vow and not pay. 6 Suffer not thy mouth to cause thy flesh to sin; neither say thou before the angel, that it was an error: wherefore should God be angry at thy voice, and destroy the work of thine hands?

PSA 61:8 So will I sing praise unto thy name for ever, that I may daily perform my vows. 66:13 I will go into thy house with burnt offerings: I will pay thee my vows, 14 Which my lips have uttered, and my mouth hath spoken, when I was in trouble.
