Exodus 20:24-25

24An altarH4196 of earthH127 shalt thou makeH6213 unto me, and shalt sacrificeH2076 on it thy burnt-offerings, and thy peace-offerings, thy sheepH6629 and thine oxenH1241: in all placesH4725 whereH834 I shall makeH6213 my nameH8034 to be rememberedH2142, I will comeH935 unto thee, and blessH1288 thee.

25And if thou makeH6213 me an altarH4196 of stoneH68, thou shalt not buildH1129 it of hewnH1496 stoneH68; for if thou lift up thy sharp tool upon it, thou hast profanedH2490 it.
