The Bible doesn’t say what the Lord did on the Wednesday of Passion Week. Scholars speculate that after two exhausting days in Jerusalem, Jesus and his disciples spent this day resting in Bethany in anticipation of Passover.
Just a short time previously, Jesus had revealed to the disciples, and the world, that he had power over death by raising Lazarus from the grave. After seeing this incredible miracle, many people in Bethany believed that Jesus was the Son of God and put their faith in him. Also in Bethany just a few nights earlier, Lazarus’ sister Mary had lovingly anointed the feet of Jesus with expensive perfume.
