30. That what any one has vowed to God, he must quickly repay.

In Solomon: “According as thou hast vowed a vow to God, delay not to pay it.”^43734373    Eccles. v. 4. Concerning this same thing in Deuteronomy: “But if thou hast vowed a vow to the Lord thy God, thou shalt not delay to pay it: because the Lord thy God inquiring shall seek it of thee; and it shall be for a sin. Thou shalt observe those things that shall go forth out of thy lips, and shalt perform the gift which thou hast spoken with thy mouth.”^43744374    Deut. xxiii. 21–23. Of this same matter in the forty-ninth Psalm: “Sacrifice to God the sacrifice of praise, and pay thy vows to the Most High.  Call upon me in the day of trouble, and I will deliver thee, and thou shalt glorify me.”^43754375    Ps. l. 14, 15. Of this same thing in the Acts of the Apostles: “Why hath Satan filled thine heart, that thou shouldst lie to the Holy Ghost, when thy estate was in thine own power? Thou hast not lied unto men, but unto God.”^43764376    Acts v. 3, 4. Also in Jeremiah: “Cursed is he who doeth the work of God negligently.”^43774377    Jer. xlviii. 10.
