Revelations 7:9 After this I beheld, and, lo, a great multitude, which no man could number, of all nations, and kindreds, and people, and tongues, stood before the throne, and before the Lamb, clothed with white robes, and palms in their hands;
This also links with IIEsdras 2:40-43:
IIEsdras 2:40 Take thy number, O Sion, and shut up those of thine that are clothed in white, which have fulfilled the law of the Lord.
:41 The number of thy children, whom thou longedst for, is fulfilled: beseech the power of the Lord, that thy people, which have been called from the beginning, may be hallowed.
:42 I Esdras saw upon the mount Sion a great people, whom I could not number, and they all praised the Lord with songs.
:43 And in the midst of them there was a young man of a high stature, taller than all the rest, and upon every one of their heads he set crowns, and was more exalted; which I marvelled at greatly.
The LORD worked through the Israelites in ancient times (IIKings 21:10, Amos 3:7, Deuteronomy 29:29) and today (Romans 3:1-2, Colossians 1:26, IPeter 2:9) to teach and instruct His will in the earth. His anointed savior, Christ, is an Israelite (Hebrews 7:14, Genesis 49:10-12, Micah 5:2, Deuteronomy 18:18-19, etc). His apostles, priests and biblical prophets were all Israelites (Amos 3:1-2, Romans 3:1-2, Romans 9:1-5, Matthew 11:25, Romans 11:1-7, etc.).
This is necessary to address and declare because in 2016 and in these last days it is the exact opposite. The biblical authorities and teachers are typically Caucasians and other non-Israelites, rather than the actual children of Israel: Romans 3:1-2. Even the majority of so-called blacks and hispanics "ordained" by governments to minister and teach the bible or that are revered as men of God, continue to instruct man's doctrines or religious traditions and dogmas. This CONFIRMS that they are not ordained and set up by the LORD: Jeremiah 23:21-22, Matthew 5:10-12, Luke 6:26, John 15:18-20, Luke 6:22-23. They have not been given the mysteries of the Lord's wisdom nor His Holy Spirit, which is evident by their works and when they speak of the LORD and Jesus Christ in error, religion, doctrines of men and lies: Mark 7:6-7.
Matthew 7:29 For he taught them as one having authority, and not as the scribes.
(Christ, and those with His Holy Spirit DO NOT teach lies, NOR the Lord's words as others do.)
