Pentecost. The Feast of Firstfruits. Feast of Weeks. There are many beautiful applications to this Feast. It symbolizes God’s first harvest of those called in this age, as a ‘kind of firstfruits.’ Christ is called the first of the firstfruits.
It represents a seven-week harvest period, the early harvest, and so is sometimes also referred to as the Feast of Weeks.
But the Holy Day we call Pentecost also has a deep significance to the law of God, both in the Old Testament and in the New.
As we follow the story of the Israelites from slavery in Egypt, we see that God provides the miracle of bread from Heaven (manna) in the second month (Exodus 16) after the Israelites had observed the Passover in Egypt. In Exodus 17 we find the miracle of water that came forth from the rock.
In the New Testament analogy, we learn that Christ is that true Bread from heaven and that Rock that quenches our thirst.
Christ was, in fact, the Old Testament lawgiver and the New Testament magnification of that Law.
So, by the time the Israelites reached the wilderness of Sinai, they were in the third month, since they kept the Passover before departing from Egypt. “In the third month after the children of Israel had gone out of the land of Egypt, on the same day, they came to the Wilderness of Sinai” (Exodus 19:1).
