Psalm 119:87–88 (ESV) … “They have almost made an end of me on earth, but I have not forsaken your precepts. In your steadfast love give me life, that I may keep the testimonies of your mouth.”
In this Psalm, David represents his life as depending on God’s mercy, not only because he was conscious of human frailty, but because he saw himself daily exposed to death in multiplied forms, or rather because he was convinced, that were God’s power withdrawn from him, he would be laid prostrate as if he were dead.
He next promises, that when he shall be again restored to life, he will not be ungrateful, but will duly acknowledge this as a blessing from God, and that not only with the tongue, but also in his whole life. As the various instances in which God helps us and delivers us from dangers are so many new lives, it is reasonable that we should dedicate to his service whatever additional time is allotted to us in this world. When the law is called the testimony of God’s mouth, by this eulogium its authority is very plainly asserted.
