Isaiah 56:2-6

ASV_Strongs(i)
  2 H835 Blessed H582 is the man H6213 that doeth H1121 this, and the son H120 of man H2388 that holdeth H8104 it fast; that keepeth H7676 the sabbath H2490 from profaning H8104 it, and keepeth H3027 his hand H6213 from doing H7451 any evil.
  3 H1121 Neither let the H5236 foreigner, H3867 that hath joined H3068 himself to Jehovah, H559 speak, H559 saying, H3068 Jehovah H914 will surely H914 separate H5971 me from his people; H5631 neither let the eunuch H559 say, H3002 Behold, I am a dry H6086 tree.
  4 H559 For thus saith H3068 Jehovah H5631 of the eunuchs H8104 that keep H7676 my sabbaths, H977 and choose H2654 the things that please H2388 me, and hold H1285 fast my covenant:
  5 H5414 Unto them will I give H1004 in my house H2346 and within my walls H3027 a memorial H8034 and a name H2896 better H1121 than of sons H1323 and of daughters; H5414 I will give H5769 them an everlasting H8034 name, H3772 that shall not be cut off.
  6 H1121 Also the H5236 foreigners H3867 that join H3068 themselves to Jehovah, H8334 to minister H157 unto him, and to love H8034 the name H3068 of Jehovah, H5650 to be his servants, H8104 every one that keepeth H7676 the sabbath H2490 from profaning H2388 it, and holdeth H1285 fast my covenant;
