A.T. Robertson Commentary Mark 11:1

"And when they draw nigh unto Jerusalem, unto Bethphage and Bethany, at the mount of Olives, he sendeth two of his disciples," — Mark 11:1 (ASV)

Unto Bethphage and Bethany (εις Βηθφαγη κα Βηθανιαν). Both together as in Lu 19:29, though Mt 21:1 mentions only Bethphage. See discussion in Matthew for this and the Mount of Olives.
