“¶ And Israel sent messengers vnto Sihon king of the Amorites, saying,”
1611 King James Version (KJV)
21:21 Sent messengers - By God's allowance, that so Sihon's malice might be the more evident and inexcusable, and their title to his country more clear in the judgment of all men, as being gotten by a just war, into which they were forced for their own defence.
