That meant the teaching of God's Word and Law to the people. But later, others would creep into the priesthood, as per our Lord Jesus in...

 

 Matthew 23:1-2 with "the scribes and Pharisees sit in Moses' seat:” Not all of these particular scribes and Pharisees our Lord Jesus was referring to were true sons of Aaron, or true Levites. These particular "scribes" of God's Law He was giving 'warning' about were of the following group:

1 Chr 2:55     And the families of the scribes which dwelt at Jabez; the Tirathites, the Shimeathites, and Suchathites. These are the Kenites that came of Hemath, the father of the house of Rechab.

     So who are the "Kenites" per God's Word? If you'll look in your Strong's Concordance, you'll discover those are the 'sons of Cain', and Cain was the first murderer (Gen.4). Those are the ones who instigated and caused Christ's crucifixion upon the cross, even while the majority of the true "house of Judah" at Jerusalem was deceived.

So as I've stated elsewhere in my Bible studies, be careful who you put the blame on for our Lord Christ's crucifixion. Our Lord Christ was very accurate in His rebuke to those of Matthew 23 and John 8. He well knew that the Kenites had crept into Moses' seat, which is the seat of God's Law. Many of true Judah fell into ignorance over those events, and many of them... still are.

 

John 12:36-42;

 

Romans 11

 

For why this had to happen, as it was part of God's Plan of Salvation. So for those of Judah that might read this, I especially ask you to consider the verses of Romans 11:14-15 and Romans 11:23-25).
     This is also 'why' God moved His Israel under responsibility of "other husbandmen", to another "nation", of... the "house of Israel" (ten tribes) in the West. That's the Western Christian Nations linked with all believers on Christ Jesus as The Saviour, everywhere, Israelites and Gentiles alike. Obviously with today's world events, that creeping in of the sons of Cain among both Judah, and the "house of Israel", has not stopped. The "tares" (false ones) will not be separated from the true "wheat" (God's children of all peoples who believe), until the time of harvest, which is at Christ's coming.

 

 Matt.13:24-30: Read.

 

 for the parable of the tares;

 

Matt.13:36-43: Read All.

 

For Christ's explanation of that parable.

 

The creeping into God's House has been going on for so many generations, that it is impossible for man to distinguish the true wheat from the tares. Only our LORD can be truly accurate in that. The Measure, for both 'houses' of Israel today, is who among them follow GOD's Word producing good fruit, vs. those who do not. By their 'fruits' (works) we shall know them.

 

 Matthew 7:15 forward: Read All

     But as our LORD said here in Isaiah 27:3, "I the LORD do keep it: I will water it every moment: lest any hurt it, I will keep it night and day." How wondrous and beautiful
