'Defend' in the Bible

{To the chief Musician, A Psalm of David.} The LORD hear thee in the day of trouble; the name of the God of Jacob defend thee;

{To the chief Musician, Altaschith, Michtam of David; when Saul sent, and they watched the house to kill him.} Deliver me from mine enemies, O my God: defend me from them that rise up against me.

Defend the poor and fatherless: do justice to the afflicted and needy.
