'Messengers' in the Bible

And the messengers of John having departed, he began to speak to the crowds concerning John: What went ye out into the wilderness to behold? a reed shaken by the wind?

And he sent messengers before his face. And having gone they entered into a village of the Samaritans that they might make ready for him.

Whether as regards Titus, he is my companion and fellow-labourer in your behalf; or our brethren, they are deputed messengers of assemblies, Christ's glory.

But was not in like manner also Rahab the harlot justified on the principle of works, when she had received the messengers and put them forth by another way?
