43 A “faithful follower” (חָסִיד, khasid) is one who does what is right in God’s eyes and remains faithful to God (see Pss 4:3; 12:1; 16:10; 31:23; 37:28; 86:2; 97:10).
44 The participial forms in the second and third lines characterize the Lord as one who typically protects the faithful and judges the proud.
45 Heb “be strong and let your heart[s] be confident.”
