'Sentry' in the Bible

The sentry called and told the king, and the king said, "If he [is] alone, good news is in his mouth." {He kept coming closer}.

{And when} he [was] at the Gate of Benjamin, there [was] {a sentry on duty} whose name [was] Irijah, the son of Shelemiah, the son of Hananiah, and he seized Jeremiah the prophet, {saying}, "You [are] deserting to the Chaldeans!"
