'Messengers' in the Bible

But he rebelled against him by sending his messengers [to] Egypt to give to him horses and a large army. Will he succeed? Will he escape doing these [things], and can he break [the] covenant and escape?

And she lusted for them {when her eyes saw them}, and she sent messengers to them [at] Chaldea.

On that day messengers will go down from {before me} in the ships to terrify unsuspecting Cush, and anguish will be in them on the day of Egypt; for look, [it is] coming!"
