Circumcision
Rom 2:11-16 For there is no respect of persons with YHVH; for as many as have sinned Torah-less shall also perish Torah-less; and as many as have sinned within the Torah shall be judged by the Torah in the Day when YHVH shall judge the secrets of men by Yeshua the Messiah of Israel according to my declaration. The hearers of the Torah are not just before YHVH, but the doers of the Torah shall be vindicated. For when gentiles (for the definition of a “gentile” see the chapter entitled "What Must I Do to Be Safe?") who do not possess a Torah scroll, do by habit the things contained in the Torah, these Torah observers, although not possessing a Torah scroll, are a Torah to each other; who show the work of the Torah (Rom 2:7 & 10) written in their hearts (Heb 8:10; Eze 36:27), their conscience also bearing witness, and their thoughts the mean while accusing or else excusing one another.
Rom 2:17-19 Behold, thou art called a Judean, and rely on the Torah, and make thy boast of YHVH, and know his will, and approve the things that are more excellent, being instructed out of the Torah; and art confident that thou thyself art a guide of the blind (2Kin 8:19), a light of them who are in darkness (in exile).
Psa 43:3-4 Send out Thy Light (the Messiah, see Luk 2:27-32 below) and Thy Truth (Your Torah, Psa 119:142); let them lead me; let them bring me back unto Thy Set-Apart Mountain, and to Thy dwelling-places. Then will I return unto the altar of Elohim, unto Eloah, my exceeding joy; and praise Thee upon the harp, O Elohim, my Elohim.
Isa 9:1-3 Now the former (Assyria during the reign of Pekah, the 18th king of Israel, 2Kin 15:29) has lightly afflicted the land of Zebulun and the land of Naphtali (in northern Israel), but the latter (Assyria during the reign of Hoshea, the last king of Israel, 2Kin 18:9-12) was more severe by the way of the sea, beyond Jordan, in Galilee of the nations. The People that departed into darkness (the People who had been removed from the land of Israel) have seen a Great Light (the Messiah, Mat 4:12-16); they that dwell in the land of the shadow of death (the "land of the shadow of death" is wherever the People of Israel were exiled), upon them hath that Great Light shined. You have increased the nation, and increased its joy.
