Leviticus 23.8 the Lord revealed the second and third “sevens” in relation to the Feast of Unleavened Bread.
The first was in verse 6 that the children of Israel were to eat unleavened bread for seven days.
Then at verse 8, the Lord said,
“But you shall offer an offering made by fire to the LORD for seven days. The seventh day shall be a holy convocation; you shall do no customary work on it” (Leviticus 23.8).
While they ate unleavened bread for seven days, the priests were also to make an offering by fire for seven days.
Then on the seventh day, Israel had a holy convocation, a time of worshiping God, and they were to rest on that day.
Some “sevens” in the Bible might be incidental, but the ones above are not, for the Lord had His reasons for what He commanded the Israelites to do.
Don,
It is likely this seventh day did not fall on the Sabbath. A New Testament example is found in John 19:31.
