'Show' in the Bible

"If your people Israel are defeated in a battle with their enemy because they have sinned against you, when they return to you and confess to you, pray, and in this Temple they ask you to show grace to them,

"Show your compassion in the presence of those who have taken them captive, so they may show compassion on them, since they are your people and your heritage, which you brought out of Egypt, from an iron fire furnace.
