What therefore does Paul intend in the following passage where he says that Elohim separated him from the koilia-hollow-belly of his mother? We know that before his spiritual rebirth he was known as Saul, a persecutor of the congregation at Yerushalaim and the faithful, and he makes mention of it all in the same passage:
Galatians 1:15
15 οτε δε ευδοκησεν ο θεος ο αφορισας με εκ κοιλιας μητρος μου και καλεσας δια της χαριτος αυτου
"εκ κοιλιας μητρος μου" ~ "from the hollow of my mother"
Galatians 1:13-16
13 For you have heard of my manner of life in time past in the religion of the Yhudim, how that beyond measure I persecuted the congregation of Elohim, and made havoc of it:
14 And I advanced in the religion of the Yhudim beyond many of mine own age among my countrymen, being more exceedingly zealous for the traditions of my fathers.
15 But when it was the good pleasure of Elohim, who separated me from the hollow [koilia] of my mother, and called me through His grace:
16 To reveal his Son in me, that I might preach him among the nations; straightway I conferred not with flesh and blood:
No doubt Paul speaks of his "mother" in this sense as Yerushalaim of Above; which he goes on to make plain for all, clearly stating for everyone who reads this epistle that it is an allegory of two covenants. Sarah represents Yerushalaim of Above while Hagar represents Yerushalaim of Below, that is, those who view the covenant and all things according to the eyes and mind of the physical and flesh minded natural man:
Galatians 4:22-27 KJV
22 For it is written, that Abraham had two sons, the one by a bondmaid, the other by a freewoman.
23 But he who was of the bondwoman was born after the flesh; but he of the freewoman was by promise.
24 Which things are an allegory: for these are the two covenants; the one from the mount Sinai, which gendereth to bondage, which is Agar [Hagar].
25 For this Agar [Hagar] is mount Sinai in Arabia, and answereth to Jerusalem which now is, [of below] and is in bondage with her children.
26 But Jerusalem which is above is free, which is the mother of us all.
27 For it is written, Rejoice, thou barren that bearest not; break forth and cry, thou that travailest not: for the desolate hath many more children than she which hath an husband [cf. Isaiah 54:1-3 Mishkan-Tabernacle imagery].
The "free woman" is Sarah, the son is Yitzchak the son of promise, and therefore Sarah represents Yerushalaim of Above. The same is true of Rachel, and so on, and so on, until Mariam, who is the final typology of Yerushalaim of Above. Yerushalaim of Above is the primary Covenant, as shown in the allegory of the passage as explained above by Paul himself, and likewise shown by the Mishkan-Tabernacle imagery which is clear in Isaiah 54:1-3 from which Paul quotes. What then does the writer speak of with the following words to Timothy? Does he speak of a natural child birth or a spiritual rebirth? Did Timothy know the sacred scriptures before he was physically born into the world? Of course not! This passage then speaks yet again of spiritual rebirth:
2 Timothy 3:15
15 And that from a babe you have known the sacred scriptures, which are able to make you wise unto salvation, through faithfulness that is in Meshiah Yeshua.
Isaiah speaks of the same herein below and this is, no doubt, where Paul receives his understanding:
Isaiah 49:1-6 Septuagint
1 Hearken to me, O islands; and attend, O nations; after a long time it shall come to pass, says YHWH, from the hollow [koilia] of my mother He has called my name: [Elohey Yisrael, Isaiah 45:3]
2 And He has made my mouth as a sharp sword, and He has hid me under the shadow of His hand; He has made me as a choice shaft, and He has hid me in His quiver.
3 And He said unto me, You are My servant, O Yisrael, and in you I will be glorified.
4 Then I said, I have labored in vain, I have given my strength for vanity, and for nothing; therefore my judgement is with YHWH, and my labor is before my Elohim.
5 And now, thus says YHWH, who formed me from the hollow [koilia] to be His own servant, to gather Yaakob and Yisrael unto Him, and I shall be gathered and glorified before YHWH, and my Elohim shall be my strength:
6 Yea, He said unto me, Is it a great thing for you to be called My servant, to establish the tribes of Yaakob, and to recover the dispersion of Yisrael? Behold, I have given you for the covenant of the peoples, for a light of the nations, that you should be for salvation to the end of the earth!
This is Meshiah speaking, who is born not of a literal virgin or maiden according to the flesh, but rather born out of the koilia, hollow, or belly, the womb of Yerushalaim Above, and that is because Messiah is formed in us when we consume the seed of the Word, (spiritual eating with the ears and eyes; hearing and reading). And his name is Elohey Yisrael, as per Isaiah 45:3 explained previously in this thread, and in him the All Yisrael and Olive Tree of YHWH shall be gathered, that the Father may be glorified in His Yisrael. Therefore Meshiah must be formed in you, as Paul himself says, O Yisrael, for both he that sanctifies and they that are sanctified are all one: for which cause he is not ashamed to call them brethren, (Hebrews 2:11), that is, they are all to become the suffering servant, Yisrael, (he must increase, but I must die off).
