ASV_Strongs(i)
  39 H251 And if thy brother H4134 be waxed poor H4376 with thee, and sell H5647 himself unto thee; thou shalt not make H5656 him to serve H5650 as a bond-servant.
  40 H7916 As a hired servant, H8453 and as a sojourner, H5647 he shall be with thee; he shall serve H8141 with thee unto the year H3104 of jubilee:
  41 H3318 then shall he go out H1121 from thee, he and his children H7725 with him, and shall return H4940 unto his own family, H272 and unto the possession H1 of his fathers H7725 shall he return.
  42 H5650 For they are my servants, H3318 whom I brought forth H776 out of the land H4714 of Egypt: H4376 they shall not be sold H4466 as H5650 bondmen.
  43 H7287 Thou shalt not rule H6531 over him with rigor, H3372 but shalt fear H430 thy God.
  44 H5650 And as for thy bondmen, H519 and thy bondmaids, H1471 whom thou shalt have; of the nations H5439 that are round about H7069 you, of them shall ye buy H5650 bondmen H519 and bondmaids.
  45 H1121 Moreover of the children H8453 of the strangers H1481 that sojourn H7069 among you, of them shall ye buy, H4940 and of their families H3205 that are with you, which they have begotten H776 in your land: H272 and they shall be your possession.
  46 H5157 And ye shall make them an inheritance H1121 for your children H310 after H3423 you, to hold H272 for a possession; H5647 of them shall ye take your bondmen H5769 for ever: H251 but over your brethren H1121 the children H3478 of Israel H7287 ye shall not rule, H376 one H251 over another, H6531 with rigor.
