Solomon taught that these things that we promise to God, but then do the opposite, God hates. We are so foolish in this.
Ecclesiastes 5:15 (KJV) 15 As he came forth of his mother’s womb, naked shall he return to go as he came, and shall take nothing of his labour, which he may carry away in his hand.
Ecclesiastes 5:4,5 (KJV) 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.
