'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 have not chosen Me, but I have chosen you and I have appointed and placed and purposefully planted you, so that you would go and bear fruit and keep on bearing, and that your fruit will remain and be lasting, so that whatever you ask of the Father in My name [as My representative] He may give to you.
