Because he hath inclined his ear unto me - answering to the second clause of Psalms 116:1, "because, He hath heard my voice, and my supplications."
Therefore will I call upon him as long as I live - answering to the first clause of Psalms 116:1. The sure proof of 'loving the Lord' is 'calling upon Him all our days,' both with prayers in time of trouble (Psalms 116:3-4) and with thanksgivings for salvation vouchsafed to us (Psalms 116:13-19) - literally, "in my days." So Isaiah 39:8.
