Matthew 10:1-4 lists the twelve apostles called by Jesus, parallel to the calling on the mountain in Mark 3:13, though with different order.

Matthew 5:1 parallels Jesus going up a mountain with disciples coming to him — the same setting as the calling of the twelve here.

Luke 6:13 is the parallel account of Jesus calling disciples and choosing twelve — directly matching this verse.

Luke 9:1 has Jesus calling the twelve together and giving authority — reminiscent of the gathering on the mountain here.
