The Aramaic adjective bishin is the plural form meaning 'evil ones' or 'wicked things' — used in the biblical Aramaic of Ezra to describe wicked men who opposed the rebuilding of Jerusalem.
In Ezra 4:12, adversaries of Israel write to the Persian king accusing the Jews of rebuilding Jerusalem, warning that they are 'wicked (bishin) and rebellious.' The charge is a lie — the builders are doing God's work — yet it illustrates a recurring biblical pattern: God's redemptive projects face slanderous opposition. The enemy's strategy of accusation before earthly kings mirrors Satan's role as 'accuser of the brethren' (Revelation 12:10). Yet God's purposes cannot ultimately be thwarted by false accusation.
