This prophecy was given during the reign of Jehoiakim (609-598 B.C.) which was 11 - 20 years before the prophecies in chapter 34. It is given to contrast the faithfulness of the Recabite family with the people of Judah. The Recabites were people who had traveled in the wilderness of Negev (1 Sam. 15:6) and were descended from Jonadab, son of Recab (35:6) who assisted Jehu in abolishing Baal worship in Israel (2 Kings 10:15-27). Their line was through the Kenites who descended from Jethro, Moses' father-in-law (Judges 1:16).
The Recabite code of conduct was similar to that of the Nazirites, who took a vow of dedication (Numbers 6, Samson was a Nazirite, Judges 13). For over 200 years, they had obeyed the commandment to not drink wine handed down from their ancestors. God compared Recabites to the other Israelites who had broken their vow to the Lord.
It is a "Keep Reading" day!
Lord, teach us to obey You. In Jesus' name, Amen.
