Psalms 84:2

My soul hath pined, yea, even fainted. The verbs are perfects, and it seems best to suppose that he is recalling the earnest longings which are even now finding satisfaction, as his feet stand in the Temple courts, and his heart and flesh sing for joy unto the living God. The latter verb denotes joyous singing, such as that with which pilgrims enlivened their journey. Cp. Jeremiah 31:12; and the cognate substantive in Psalms 42:4. Soul, heart, and flesh, the emotions, the reason and the will, with the living organism of the body through which they act, make up the whole man. See Psalms 16:9; Psalms 73:26; and cp. 1 Thessalonians 5:23.

the living God The same phrase (El chay) as in Psalms 42:2. God Himself is the final object of desire: the Temple is only the means of realising His Presence.
