The Baptist John was expecting a warrior messiah, a king. And, hence, His puzzlement-expect another? He was clueless that the Messiah, the Christ, was to die.
No one knew at that time that Christ was going to be put to death. The 12 were clueless. John the Baptist was clueless, witness his puzzlement that he was in prison, and his message to the Lord. "What the heck is happening?". He was expecting the warrior King Messiah, not a suffering servant. It was not until the Sanhedrin declared the Lord Jesus Christ's destruction, that the Lord Jesus Christ revealed that He was going to die. Again, the 12 were clueless. Everyone was. The passover lamb did not represent "bearing sin," and a lamb was never the sin offering victim. Nor was it "the sin of the world" that the scapegoat bore away-it was the sins of Israel, per Lev. 16:21 KJV. The "bearing of the sin of the world" is not a reference to a prophecy, pointing to Calvary, but a revelation of what the Lord Jesus Christ was during His earthly ministry. "taketh away"-taking up and carrying burdens, not a "sacrificial" term here.
His earthly ministry-sin bearer, in the sense of taking up and carrying burdens-his groans and tears at the grave of his friend Lazarus....He took up and bore the burden of human sin; not, during His earthly life as to guilt(that was not until Calvary), but as to sufferings and sorrows it brought upon all of mankind:
Is. 53:7 KJV
He was oppressed, and he was afflicted, yet he opened not his mouth: he is brought as a lamb to the slaughter, and as a sheep before her shearers is dumb, so he openeth not his mouth.
No sacrificial language is intended here, as slaughter merely means "shambles," It foretold of the Christ's earthly life of "humbling Himself", and suffering.
I challenge those "rabble rousers," who think us "dispie" and/or MAD wackos, need to be drugged up, and taught to chant, "It all says the same thing....It all says the same thing...It all says the same thing....Cuz Professor Judas/Demas told me so....I'll be just fine.........," like them, to show us, chapter and verse, where the 12 ever knew about the Lord Jesus Christ's death, until it was revealed nearly 3 years after John 1:29 KJV. Show us. I showed you scripture that they had no idea. Peter tried to prevent the Lord's death........................
I know, I know....MAD is a sect/cult......We will pray for you, my dear, misguided, mean spirited John W.................
"And the beat goes on..........................."
