Found at Quotidian Grace's place, and others:

Matthew 6:4
"..so that your alms may be in secret; and your Father who sees in secret will reward you.

Mark 6:4
"And Jesus said to them, 'A prophet is not without honor, except in his own country, and in his own house.'"

Luke 6:4
"...how he entered the house of God, and took and ate the bread of the Presence, which is not lawful for any but the priests to eat, and also gave it to those with him?"

John 6:4
"Now the Passover, the feast of the Jews, was at hand."

A rather strange little collection of Jesus' sayings, doncha think?
