Besides the good shepherd, what else did Jesus call himself in John 10?

Answer: The gate

Jesus said, 'I am the gate for the sheep' (KJV 'door'); whoever enters through Him will be saved and find pasture.

“So He said to them again, “Truly, truly, I tell you, I am the gate for the sheep. All who came before Me were thieves and robbers, but the sheep did not listen to them. I am the gate. If anyone enters through Me, he will be saved. He will come in and go out and find pasture.”— John 10:7-9 (BSB)
