'Presence' in the Bible

How was it that he went into the House of God during the lifetime of Abiathar the high priest and ate the Bread of the Presence, which was not lawful for anyone but the priests to eat, and gave some of it to his companions?"

Six days later, Jesus took with Him Peter, James, and John, and brought them alone, apart from the rest, up a high mountain; and in their presence His appearance underwent a change.
