'Messenger' in the Bible

You yourselves are my witnesses that I stated, ‘I am not the Christ (the Messiah, the Anointed),’ but, ‘I have [only] been sent ahead of Him [as His appointed forerunner and messenger to announce and proclaim His coming].’

for a messenger at a set time was going down in the pool, and was troubling the water, the first then having gone in after the troubling of the water, became whole of whatever sickness he was held.

You do not have His word (Scripture) abiding in you [actually living in your hearts and minds], because you do not believe in Him whom He has sent.

Jesus answered, “This is the work of God: that you believe [adhere to, trust in, rely on, and have faith] in the One whom He has sent.”

I knew that You always hear Me and listen to Me; but I have said this because of the people standing around, so that they may believe that You have sent Me [and that You have made Me Your representative].”

the multitude, therefore, having stood and heard, were saying that there hath been thunder; others said, 'A messenger hath spoken to him.'

“I assure you: A slave is not greater than his master, and a messenger is not greater than the one who sent him.

I assure you and most solemnly say to you, the one who receives and welcomes whomever I send receives Me; and the one who receives Me receives Him who sent Me [in that same way].”
