It is so difficult trying to describe this treasure to you seekers when you probably don’t have a Hebrew Bible to reference, but I’ll do my best. This treasure is in Exodus chapter 25. The first bracket is in verse 16, which reads in English and Hebrew:

Notice that the Alef Tav (אֵת) is before “the Testimony” (הָעֵדֻת) in this occurrence. (Reading from right to left in the Hebrew.)
The next verse (17) begins describing the mercy seat (kapporet-the covering. Have you heard of a kippah? The little beanie that observant Jews wear? That is their covering, their kippah. It’s the same root word for the covering of the ark of the covenant.).
Once the description is articulated for the mercy seat, YHVH gives us the second “bracket”. The Alef Tav (אֵת) is behind “the Testimony” (הָעֵדֻת) this time. Take a look:

The Testimony that YHVH is speaking of are the tablets, written with His own finger, of the Ten Commandments. Is there any doubt that Yeshua is the Testimony? The Ten Commandments that will be inside the ark forever? The ark that Yeshua’s blood spilled on at His sacrifice? It all ties together perfectly!

Please forgive my shortcomings when it comes to explaining things. I often have a hard time describing things that are in my brain. I hope that I described this treasure well enough. This is a big one!
Thank you for stopping by. 😇 May you be blessed as you bless YHVH. 💜
