David
Psalm 63:4ESV·traditional attribution

So I will bless you as long as I live; in your name I will lift up my hands.

John Calvin Reformed @genevareformer

PSALM 63 The following psalm cannot so properly be said to consist of prayers as of a variety of pious meditations, which comforted the mind of David under dangers, anxieties, and troubles of a severe description. It contains the vows too which he made to God in the distress occasioned by the alarming circumstances in which he was placed.

C.H. Spurgeon Reformed Baptist @princeofpreachers

Thus will I bless thee while I live. As I now bless thee so will I ever do; or rather, so as thou shalt reveal thy lovingkindness to me, I will in return continue to extol thee. While we live we will love. If we see no cause to rejoice in our estate, we shall always have reason for rejoicing in the Lord.

Matthew Henry Presbyterian @wholebiblehenry

How soon are David's complaints and prayers turned into praises and thanksgivings! After two verses that express his desire in seeking God, here are some that express his joy and satisfaction in having found him. Faithful prayers may quickly be turned into joyful praises, if it be not our own fault.
