▼ The Hebrew noun is an abstract plural. The word often refers metonymically to the happiness that God-given security and prosperity produce (see Pss 1:1, 3; 2:12; 34:9; 65:4; 84:12; 89:15; 106:3; 112:1; 127:5; 128:1; 144:15).

▼ One who treats the poor properly. The psalmist is characterizing himself as such an individual and supplying a reason why God has responded favorably to his prayer. The Lord’s attitude toward the merciful mirrors their treatment of the poor.

▼ Heb “in the day of trouble” (see Ps 27:5).

▼ That is, the one who has been kind to the poor. The prefixed verbal form could be taken as jussive of prayer (“may the Lord deliver,” see v. 2), but the preceding parallel line is a declaration of fact, not a prayer per se. The imperfect can be taken here as future (“will deliver,” cf. NEB, NASB) or as generalizing (“delivers,” cf. NIV, NRSV). The parallel line, which has a generalizing tone, favors the latter. At the same time, though the psalmist uses a generalizing style here, he clearly has himself primarily in view.
