Verse 4. - Thus will I bless thee while I live: I will lift up my hands in thy Name (comp. Psalm 104:33; Psalm 146:2). The purpose of man's creation, the end of his being, his main employment throughout eternity, is the praise of God.

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!Thus will I bless thee while I live,.... With his whole heart and soul, as he had sought after him, and as under a sense of his lovingkindness; and as he now praised him with his lips, so he determined to do as long as he had life and being; by proclaiming his blessedness, by ascribing blessing and honour to him, and by giving him the glory of all mercies temporal and spiritual;

I will lift up my hands in thy name; not against his enemies, against those that fought against him, as Kimchi and Ben Melech interpret it, but unto God in heaven; and that not as a gesture used in swearing, but either in blessing, as Aben Ezra observes; so the high priest lifted up his hands when he blessed the people; or in prayer, or in both, so Jarchi's note is, to pray and to praise; See Gill on Psalm 28:2. The Targum is,

"in the name of thy Word I will spread out my hands in prayer for the world to come;''

that is, in the name of the Messiah, the essential Word, in whose name prayer is to be made, and whereby it becomes prevalent and successful; see John 14:13. This is a prayer gesture; See Gill on Psalm 28:2.
