Exodus 12:45

תושב A TOLERATED SOJOURNER — this means a stranger who has settled in Palestine (having undertaken to observe the seven precepts of the “Sons of Noah”). ושכיר AND A HIRED SERVANT — a heathen. But why need Scripture state at all that these (the תושב and the שכיר) may not eat of the Passover lamb? These are uncircumcised and it is said (v. 48) “And no uncircumcised person shall eat thereof”? But it refers to such a one as a circumcised Arabian or a circumcised Gibeonite who is a settler or a hired servant (Mekhilta; Yevamot 71a).

תּוֹשָׁ֥ב וְשָׂכִ֖יר לֹא־יֹ֥אכַל בּֽוֹ׃

A foreigner and a hired servant shall not eat of it.
