'Curse' in the Bible

But not a man put his hand to his mouth for fear of the curse.

Go now and put Amalek to the sword, putting to the curse all they have, without mercy: put to death every man and woman, every child and baby at the breast, every ox and sheep, camel and ass.

But Saul and the people did not put Agag to death, and they kept the best of the sheep and the oxen and the fat beasts and the lambs, and whatever was good, not desiring to put them to the curse: but everything which was bad and of no use they put to the curse.

And the Lord sent you on a journey and said, Go and put to the curse those sinners, the Amalekites, fighting against them till every one is dead.

But the people took some of their goods, sheep and oxen, the chief of the things which were put to the curse, to make an offering of them to the Lord your God in Gilgal.
