'Treading' in the Bible

Go up, ye horses; and boast yourselves, ye chariots, And go forth, ye mighty, Cush and Phut handling the shield, And Lud handling -- treading the bow.

Set yourselves in array against Babylon round about, All ye treading a bow, Shoot at her, have no pity on the arrow, For against Jehovah she hath sinned.

Summon unto Babylon archers, all treading the bow, Encamp against her round about, Let her have no escape; Recompense to her according to her work, According to all that she did -- do to her, For unto Jehovah she hath been proud, Unto the Holy One of Israel.
