Псалми 138:3

There are two things for which the poet gives thanks to God: He has answered him in the days of trouble connected with his persecution by Saul and in all distresses; and by raising him to the throne, and granting him victory upon victory, and promising him the everlasting possession of the throne, He has filled him with a proud courage, so that lofty feeling has taken up its abode in his soul, which was formerly fearful about help. Just as רהב signifies impetuosity, vehemence, and then also a monster, so הרהיב signifies both to break in upon one violently and overpowerlingly (Sol 6:5; cf. Syriac arheb, Arabic arhaba, to terrify), and to make any one courageous, bold, and confident of victory. בּנפשׁי עז forms a corollary to the verb that is marked by Mugrash or Dech: so that in my soul there was עז, i.e., power, viz., a consciousness of power (cf. Jdg 5:21). The thanksgiving, which he, the king of the promise, offers to God on account of this, will be transmitted to all the kings of the earth when they shall hear (שׁמעוּ in the sense of a fut. exactum) the words of His mouth, i.e., the divine אמרה, and they shall sing of (שׁיר with בּ, like דּבּר בּ in Psa 87:3, שׂיח בּ in Psa 105:2 and frequently, הלּל בּ in Psa 44:9, הזכּיר בּ in Psa 20:8, and the like) the ways of the God of the history of salvation, they shall sing that great is the glory of Jahve. Psa 138:6 tells us by what means He has so super-gloriously manifested Himself in His leadings of David. He has shown Himself to be the Exalted One who is His all-embracing rule does not leave the lowly (cf. David's confessions in Psa 131:1; Sa2 6:22) unnoticed (Psa 113:6), but on the contrary makes him the especial object of His regard; and on the other hand even from afar (cf. Psa 139:2) He sees through (ידע as in Psa 9…

It does not appear, nor is it material to enquire, upon what occasion David penned this psalm; but in it, I. He looks back with thankfulness upon the experiences he had had of God's goodness to him (Psa 138:1-3). II. He looks forward with comfort, in hopes, 1. That others would go on to praise God like him (Psa 138:4, Psa 138:5). 2. That God would go on to do good to him (Psa 138:6-8). In singing this psalm we must in like manner devote ourselves to God's praise and glory and repose ourselves in his power and goodness. A psalm of David.
