Psa 18:50 | NET2full | STEP | He gives his king magnificent victories ; he is faithful to his chosen ruler , to David and his descendants forever .”

‏ Psalms 18:50

50 He ^{▼▼tn Or “the one who.”} gives his king magnificent victories; ^{▼▼tn Heb “magnifies the victories of his king.” “His king” refers to the psalmist, the Davidic king whom God has chosen to rule Israel.}
he is faithful ^{▼▼tn Heb “[the one who] does loyalty.”} to his chosen ruler, ^{▼▼tn Heb “his anointed [one],” i.e., the psalmist/Davidic king. See Ps 2:2.}
to David and his descendants ^{▼▼tn Or “offspring”; Heb “seed.”} forever.” ^{▼▼sn If David is the author of the psalm (see the superscription), then he here anticipates that God will continue to demonstrate loyalty to his descendants who succeed him. If the author is a later Davidic king, then he views the divine favor he has experienced as the outworking of God’s faithful promises to David his ancestor.}
