In most Read the Bible plans, the ship runs aground on the two books of Leviticus and Numbers.
Leviticus is a sort of worship manual for the Tabernacle. Our best advice is to read lightly – don’t get bogged down if you find that this is difficult. but do take note. Ask yourself why is this necessary? Why is there a “fellowship offering” that involves a sort of picnic? (ch 7) Why is the 2nd greatest commandment found here? (19:18) What is the point of the two goats on the Day of Atonement? (ch 16)
Numbers contains a lot of genealogy and census data. There are also some interesting stories: the talking donkey (ch 22), the bronze serpent (21), where worship lived among the people (2:17), and others.
So remember this is a “guilt free” reading. Skim or skip if you must, but do at leach touch on the text in these books.
