Thus will I bless thee while I live: I will lift up my hands in thy name.

Jamieson-Fausset-Brown Bible Commentary

4. Thus-literally, "Truly."

will I bless-praise Thee (Ps 34:1).

lift up my hands-in worship (compare Ps 28:2).

in thy name-in praise of Thy perfections.

Matthew Henry's Concise Commentary

63:3-6 Even in affliction we need not want matter for praise. When this is the regular frame of a believer's mind, he values the loving-kindness of God more than life. God's loving-kindness is our spiritual life, and that is better than temporal life. We must praise God with joyful lips; we must address ourselves to the duties of religion with cheerfulness, and speak forth the praises of God from a principle of holy joy. Praising lips must be joyful lips. David was in continual danger; care and fear held his eyes waking, and gave him wearisome nights; but he comforted himself with thoughts of God. The mercies of God, when called to mind in the night watches, support the soul, making darkness cheerful. How happy will be that last morning, when the believer, awaking up after the Divine likeness, shall be satisfied with all the fulness of God, and praise him with joyful lips, where there is no night, and where sorrow and sighing flee away!
