Psalms 56:13

For thou hast delivered my soul from death: [wilt] not [thou deliver] my feet from falling, that I may walk before God in the light of the living?

Ver. 13. For thou hast delivered my soul from death] Which was the very thing I begged of thee when I was at worst, viz. that thou wouldest save my life, which then lay at stake; I also then solemnly took upon me such and such engagements, which lie upon me as so many debts, and I am in pain till I have paid them. This if I shall do effectually,

Wilt not thou deliver my feet from falling] Yea, I know thou wilt, Lord, for every former favour of thine is a pledge of a future.

That I may walk before God in the light of the living?] Called elsewhere the land of the living; that is, in this present life, spending the span of it in thy fear, and labouring to be every whit as good as I vowed to be at the time when I was in great distress and danger. Pliny, in an Epistle of his to one that desired rules from him how to order his life aright, I will, saith he, give you one rule that shall be instead of a thousand, Ut tales esse perseveremus sani, quales nos futures esse profitemur infirmi, i.e. That you hold out to be such when well as you promised to be the time when weak and sick, &c.
