In the podcast I mistakenly say that the New Moon was a weekly feast. That is incorrect. The New Moon was a monthly feast- Numbers 28:11-15. It is alluded to in the OT in several places like I Sam. 20:5, 18, 24, 27; II Kings 4:23; Isaiah 1:13-14; Amos 8:5.
What does Psalm 81 teach us about God?
1. God is worthy of praise- 81:1-3
2. God rescued Israel out of Egypt- 81:6-7, 10
3. God asks that His people listen to Him- 81:8- and serve Him alone- 81:9
4. God longs for His people to do the right thing and to bless them- 81:8, 13-16.
Jesus fulfills Psalm 81
81:8, 11, 13 God's people must listen to Jesus- Matt. 17:5
81:8, 13 Jesus longs for us to be saved- Matt. 23:37-39; Luke 13:34-35
81:10, 16 Jesus is the ultimate bread who can satisfy our deepest hunger- John 6:35
These are just a few of the ideas from this Psalm.
