Sin offering in which they laid hands on the sacrifice and made transfer of sins to the animal, sacrificed the animal and then washed the sacrifice is likened to Acts 2:38:
And Kĕpha said to them, “Repent, and let each one of you be immersed in the Name of יהושע Messiah for the forgiveness of sins.1 And you shall receive the gift of the Set-apart Spirit.
Rev 5:8 And when he had taken the book, the four beasts and four and twenty elders fell down before the Lamb, having every one of them harps, and golden vials full of odours, which are the prayers of saints.
Psa 141:2 Let my prayer be set forth before thee as incense; and the lifting up of my hands as the evening sacrifice.
Paul refers to himself (his life and ministry) as being poured out like a drink offering to the
service of YHVH while he was imprisoned (Philippians 2:17 and 2Timothy 4:6).
Now turn to and read Numbers 28:3. At the end of the
verse, we read the following speaking about the twice
daily sacrifices, “you shall be careful to offer to Me at
their appointed time” (NKJV). The word “appointed time”
in the Hebrew is “moed” and is a reference to anything
that YHVH commands his people to do at a set and regular time. These are regular times when he wants to meet
with his people. Examples of a moed would be the weekly
Sabbath and YHVH’s annual sabbaths, such as Passover/
Unleavened Bread, Pentecost, Trumpets, Atonement, Tabernacles and the Eighth Day (Shemini Atzeret). So what is
YHVH saying here? He is saying that the twice daily burnt
offerings were appointed or set times when he chose to
meet with his people. (Wow, that is amazing to consider...that our time with Abba is appointed and actually commanded and we are doing His service as a living sacrifice when we fulfill that time with Him!!)
