'Appointed' 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 an angel of the Lord went down into the pool at appointed seasons and stirred up the water; the first one to go in after the water was stirred was healed of his disease.]

But the testimony which I have is far greater than the testimony of John; for the works that the Father has given Me to finish—the very same works [that is, the miracles and proofs of My deity] that I am [now] doing—testify about Me, [by providing evidence] that the Father has sent Me.

You did not choose Me, but I chose you. I appointed you that you should go out and produce fruit and that your fruit should remain, so that whatever you ask the Father in My name, He will give you.
