Psalms 63:3

Because thy lovingkindness&c. R.V. renders, For thy lovingkindness&c., a further reason for the longing of Psalms 63:1. But it is best to retain the rendering of the A.V. He has waited to see God's power and glory, yet after all it is the lovingkindness of which he has personal experience that tunes his lips to praise. When Moses desired to see God's glory, he was granted a revelation of His goodness(Exodus 33:18 ff). It is better than life, than that which men count most precious, for without it life would be a desert. His life was threatened, but the danger fades out of sight in the consciousness of God's love. Note the connexion of God's strength and lovingkindness (Psalms 63:2), as in Psalms 62:11-12.

shall praise thee Shall laud thee, a different word from that in Psalms 63:5. The word is supposed to be a proof of the late date of the Psalm, as it is an Aramaic word, and is found elsewhere only in the later parts of the O.T. But it is precarious to argue from a single word, when the remains of Heb. literature are so comparatively scanty.
