'Siegeworks' in the Bible

Only the trees which you know are not fruit trees you shall destroy and cut down, that you may construct siegeworks against the city that is making war with you until it falls.

There was a small city with few men in it and a great king came to it, surrounded it and constructed large siegeworks against it.

I will camp against you encircling you,And I will set siegeworks against you,And I will raise up battle towers against you.
