Numbers 35:30-34

30Whoever killethH5221 any personH5315, the murdererH7523 shall be put to deathH7523 by the mouthH6310 of witnessesH5707: but oneH259 witnessH5707 shall not testifyH6030 against any personH5315 to cause him to dieH4191. 31Moreover ye shall takeH3947 no satisfactionH3724 for the lifeH5315 of a murdererH7523, who is guiltyH7563 of deathH4191: but he shall be surelyH4191 put to deathH4191.1 32And ye shall takeH3947 no satisfactionH3724 for him that hath fledH5127 to the cityH5892 of his refugeH4733, that he should come againH7725 to dwellH3427 in the landH776, until the deathH4194 of the priestH3548. 33So ye shall not polluteH2610 the landH776 in which ye are : for bloodH1818 it defilethH2610 the landH776: and the landH776 cannot be cleansedH3722 of the bloodH1818 that is shedH8210 in it, but by the bloodH1818 of him that shedH8210 it.2 34DefileH2930 not therefore the landH776 which ye shall inhabitH3427, in whichH8432 I dwellH7931: for I the LORDH3068 dwellH7931 amongH8432 the childrenH1121 of IsraelH3478.
