Matthew 1:18

Τοῦ δὲ Ἰησοῦ Χριστοῦ ἡ γέννησις οὕτως ἦν· μνηστευθείσης γὰρ τῆς μητρὸς αὐτοῦ Μαρίας τῷ Ἰωσήφ, πρὶν ἢ συνελθεῖν αὐτούς, εὑρέθη ἐν γαστρὶ ἔχουσα ἐκ Πνεύματος Ἁγίου.

RBT Hebrew Literal:

Discovery of Genesis

And the Genesis of the Salvation, Anointed One, she was in this way, she who was wooed of the Mother of himself of Bitter-Rebel ("Mary")² to the He Adds ("Joseph"). Before the coming together of themselves, she was discovered within a belly, she who is holding from out of a spirit of a holy one.³

The Genesis

"And she who is holding within a belly she is also cawing, her who is in childbirth pains, and she who is being touchstone-tormented to bring forth."

(Revelation 12:2 RBT)

Julia Smith Literal 1876 Translation:
And the generation of Jesus Christ was thus: for Mary his mother having been betrothed to Joseph, before they came together she was found with child by the Holy Ghost.

LITV Translation:
And the birth of Jesus Christ was this way (for His mother Mary had been betrothed to Joseph) before they came together, she was discovered to be pregnant in womb by the Holy Spirit.

ESV Translation:
Now the birth of Jesus Christ took place in this way. When his mother Mary had been betrothed to Joseph, before they came together she was found to be with child from the Holy Spirit.

Footnotes

2

Greek μνηστευθείσης τῆς μητρὸς αὐτοῦ Μαρίας. Every one of these words are in the genitive case.

• of she who is wooed
• of the mother
• of himself
• of Mary/Bitter-Rebel

μνηστευθείσης "her who was wooed and won" is a participle noun in the genitive, aorist tense.

Discovered in a Belly

Greek ἐκ πνεύματος ἁγίου. from out of a spirit of a holy one. There is no definite article "the" present in this text, therefore capitalizing the words or adding "the" to the text is less than accurate. ἁγίου which is also translated as "saint" is in the genitive case.

Greek hagios. #G40. set-apart, different, holy, sacred. Used in the Septuagint for the Hebrew qadosh which means “set-apart, holy”.

“The fundamental (core) meaning of 40 (hágios) is “different” – thus a temple in the 1st century was hagios (“holy”)

Holding within a Belly or Found within a Belly?

The literal of this phrase is "she was found in a belly she who is holding" 

ἐν γαστρὶ "within a belly." Strongs #1064 γαστήρ (gastér) a word from which we get all the gastro- words. The significance of this word lies in the fact that there exists a more appropriate word for "womb" #3388 métra.

Certain biases will lean toward translating ἐν γαστρὶ ἔχουσα as "holding within a belly" as it is normal for verbs to follow objects in Greek. However, the verb that follows "in a belly" is in participle form, which is not so typical, if "belly" was meant to be the object. Moreover, Ancient Greek literature and texts often preferred precise terms to describe specific states or conditions, and ἔγκυος was the accurate term for pregnancy, not "holding" ἔχουσα. But even if that were the intention of the writer here, it leaves the prior verb εὑρέθη "she was found" an aorist indicitive active verb without any object.  She was found....where?

Overall, there is quite a forceful and awkward shift to go from 

"she was found in a belly she who is holding"

to

"she was discovered to be pregnant in womb"

since, 1) there is no infinitive κυεῖν "to be pregnant" in this verse and 2) there is no word μήτρα "womb/matrix" either.

Luke, when speaking of Mary uses ἐγκύῳ "pregnant" which literally means "swelling inside" from a word κύῳ meaning "wave/swell" of a sea or lake.
