The Gentile converts had the same law.

The same law applies both to the native-born and to the foreigner residing among you.”
Leviticus 7:7

Leviticus 24:22
You are to have the same law for the foreigner and the native-born. I am the Lord your God.’”
Numbers 15:16
The same laws and regulations will apply both to you and to the foreigner residing among you.’”
Numbers 15:29

Ephesians 2:15
This verse is not correctly translated. See commentary below.
by setting aside in his flesh the law with its commands and regulations. His purpose was to create in himself one new humanity out of the two, thus making peace,
1 Timothy 1:7
They want to be teachers of the law, but they do not know what they are talking about or what they so confidently affirm.
1 Timothy 1:8

You completely miss the very point of Paul's Apostleship; an Apostleship distinct from that of the Twelve, Gal. 2:7-9.

Neither Circumcision in the flesh made by hands, nor Uncircumcision in the flesh, apply in this age, Gal. 5:6.
Per Rom. 1-3; 9-11, the believing remnant of Israel was sealed by God, as His, for their having found (believed on) His Son, Rom. 10.
He then concluded the rest of Israel blind, and temporarily set aside His dealings with that nation according to their covenants and promises, for their unbelief, Rom. 11.
Per those passages, the nation of Israel was concluded under the power of sin with the Gentiles, that God - during this Mystery Age - might not only have mercy on both, and this; absent of the Circumcision distinction, but given this Age's own purpose in Christ, Rom. 8:29-30; Eph. 1; Eph. 3; 2 Tm. 1:8-11.
