Charles H. Spurgeon on Psalms 116:14

A man that would have his credit as to the truth of his word kept up, would choose those to be witnesses of his performing who were witnesses of his promising. I think David took this heed in his rendering and paying his vows: "I will do it, "saith he, "now in the presence of all his people." The people were witnesses to his straits, prayers, and vows; and he will honour religion by performing in their sight what he sealed, signed, and delivered as his vow to the Lord. Seek not more witnesses than providence makes conscious of thy vows, lest this be interpreted ostentation and vain self glorying: take so many, lest the good example be lost, or thou suspected of falsifying thy vow. Briefly and plainly: Didst thou on a sick bed make thy vow before thy family, and before the neighbourhood? Be careful to perform it before them; let them see thou art what thou vowedst to be. This care in thy vow will be a means to make it most to the advantage of religion, whilst all that heard or knew thy vow bear thee testimony that thou art thankful, and thus thou givest others occasion to glorify thy Father who is in heaven. Henry Hurst (1690) in "The Morning Exercises."
