2 Kings 20:5 -- "Go back and say to Hezekiah, the ruler of my people, The Lord, the God of David your father, says, Your prayer has come to my ears, and I have seen your weeping; see, I will make you well: on the third day you will go up to the temple of the Lord." ... Now Hezekiah said to Isaiah, "What will be the sign that the LORD will heal me, and that I shall go up to the house of the LORD the third day?"
St. Cyprian of Carthage pointed in one of his books to Hosea 6:2 -- "After two days He will revive us; we shall rise again on the third day, that we may live before His Face."
So this would mean that the Lord's Resurrection is foreshadowing all our resurrection.
He also pointed out Exodus 19:10-11 -- "And the Lord said unto Moses, 'Go down and testify to the people, and sanctify them to-day and to-morrow; and let them wash their garments, and let them be prepared against the day after to-morrow. For on the third day the Lord will come down on Mount Sinai.' "
And of course, Jonah. And of course, there's a ton of "three days" in the Gospels themselves, foreshadowing the Resurrection.
