'Mount' in the Bible

Then they returned to Jerusalem from the mount called Olivet, which is near Jerusalem, a Sabbath day’s journey away.

“After forty years had passed, an angel appeared to him in the wilderness of Mount Sinai, in the flame of a burning thorn bush.

This is the one who was in the congregation in the wilderness together with the angel who was speaking to him on Mount Sinai, and who was with our fathers; and he received living oracles to pass on to you.
