Phinehas Leads Israel's Army Against Midianby emmanuel_higgins

Numbers 31:5

So there were delivered out of the thousands of Israel, a thousand of every tribe, twelve thousand armed for war.

Twelve thousand armed men were delivered out of the thousands of Israel for the war against Midian, one thousand furnished from each tribe. They were chosen and sent out in obedience to God's command. The command they obeyed was to avenge Israel.

Their work was to execute God's judgment as His instruments, with zeal for His glory and not to gratify personal malice or revenge.
