Midrash for Bava Metzia 118:12
תנו רבנן המאנה את הגר עובר בשלשה לאוין והלוחצו עובר בשנים
a proselyte being included in <i>'fellowman</i>.' But for 'oppression' also three are written, viz., <i>and thou shalt not oppress him,<span class="x" onmousemove="('comment',' Ex. XXII, 20. ');"><sup>21</sup></span></i> Also thou shalt not oppress a stranger,<span class="x" onmousemove="('comment',' Ex. XXIII, 9. ');"><sup>22</sup></span>
Ein Yaakov (Glick Edition)
Our Rabbis were taught: He who annoys a stranger transgresses three negative commandments, and he who oppresses him transgresses two. Let us see, Regarding annoying, there are three negative commandments, (Ex. 22, 20; Lev. 19, 33 and 25, 17). If so, then there are three negative commandments concerning oppression also (namely, Ex. 22, 20; 23, 9 and 22, 24) — which include also the stranger. We must therefore say that in both cases, he transgresses three negative commandments.
