'Devoting' in the Bible

and we devote them, as we have done to Sihon king of Heshbon, devoting every city, men, the women, and the infants;

Thou dost surely smite the inhabitants of that city by the mouth of the sword; devoting it, and all that is in it, even its cattle, by the mouth of the sword;

But the king will rejoice in God;Everyone who swears by Him [honoring the true God, acknowledging His authority and majesty] will glory,For the mouths of those who speak lies will be stopped.
