Andrew shows is faith and knowledge about the miracle that the prophet Elisha performed:
A man came from Baal-shalishah, bringing food from the first fruits to the man of God: twenty loaves of barley and fresh ears of grain in his sack. Elisha said, “Give it to the people and let them eat.” But his servant said, “How can I set this before a hundred people?” So he repeated, “Give it to the people and let them eat, for thus says the Lord, ‘They shall eat and have some left.’” He set it before them, they ate, and had some left, according to the word of the Lord.
2 Kings 4:42-44
Note that the first fruits is mentioned in Leviticus as a important festival soon after Passover:
. . . bring to the priest a sheaf of the first grain you harvest. He is to wave the sheaf before the LORD so it will be accepted on your behalf; the priest is to wave it on the day after the Sabbath. On the day you wave the sheaf, you must sacrifice as a burnt offering to the LORD a lamb a year old without defect . . .
Leviticus 23:10-12
Sounds like another parallel to the Eucharist to me.
