'Save' in the Bible

So Jonathan said to {his armor bearer}, "Come, let us go over to the garrisons of these uncircumcised; perhaps Yahweh will act for us, for there is no hindrance for Yahweh to save by many or by few."

Then Saul sent messengers to David's house to guard him and to kill him in the morning, but Michal his wife told David, saying, "If {you do not save your life} tonight, [then] tomorrow you [will be] killed!"

So David inquired of Yahweh, saying, "Shall I go and attack these Philistines?" And Yahweh said to David, "Go and attack the Philistines and save Keilah."
