Psalms 3:9

Blessing. Abundance of grace is promised to God's servants, who must look up to him for salvation. David gives thanks for the victory, though he grieved at his son's death. (Worthington) --- He shewed proofs of the greatest clemency on this occasion. It is evident, from this psalm being inserted before many which regard Saul, that no chronological order is observed. (Calmet) --- Selah occurs a third time here, as some may have ended the lecture at one, while others ordered it to be continued to another, or even to the 3d and 5th verse of the next psalm, if that be its real import. (Haydock)
