Hebrews 3 and 4 – It says Messiah is an "Apostle?" 2018

Heb 3:1
Therefore, holy brethren, partakers of a heavenly calling, consider Jesus, the Apostle and High Priest of our confession.

Heb 3:2
He was faithful to Him who appointed Him, as Moses also was in all His house.

How is Yeshua an "Apostle?" This is one word that is probably mischaracterized in many churches. The Greek word for Apostle is Apostolos which means "messenger" or "one sent from Elohim." It essentially means "missionary." Yeshua is faithful to Elohim. The comparison is made to Moses and his faithfulness. This is a quote from

Numbers 12:6-8 He said, “Hear now My words: If there is a prophet among you, I, the LORD, shall make Myself known to him in a vision. I shall speak with him in a dream. 7“Not so, with My servant Moses, He is faithful in all My household; 8With him I speak mouth to mouth, Even openly, and not in dark sayings, And he beholds the form of the LORD. Why then were you not afraid To speak against My servant, against Moses?”
In this section of Hebrews, Paul is speaking of Israel wandering the wilderness and the fact that many were not allowed to enter into His "rest." In this context, the meaning of His "rest" is the Land of Milk and Honey promised to Israel. This is the "Kingdom of Heaven" or the "Kingdom of the Heavens."

In this chapter, the author is going to use this "rest" in a sense to refer to a time when we have fellowship with Him. This chapter also contains that which most Christian Bible teachers tell you does not exist. This chapter contains the "New Testament" (Brit Hadashah) command to keep the Sabbath!
