Exodus 20:25-26

Wycliffe Bible

²⁵ That if thou shalt make an altar of stone to me, thou shalt not build it of stones hewn (And if thou make an altar out of stones for me, thou shalt not build it out of cut stones); for if thou shalt raise thy knife thereupon, or (any) other instrument wherewith blood may be shed out, it shall be polluted.

²⁶ Thou shalt not go up by degrees to mine altar, lest thy filth(hood) be showed. (Thou shalt not go up to my altar by steps, lest thy nakedness should be shown.)
