Deuteronomy 27:5

And there shalt thou build an altar unto the LORD thy God, an altar of stones: thou shalt not lift up any iron tool upon them.

There shall you build an altar to Yahweh your God, an altar of stones: you shall lift up no iron [tool] on them.

And there shalt thou build an altar unto Jehovah thy God, an altar of stones: thou shalt lift up no iron `tool' upon them.

and built there an altar to Jehovah thy God, an altar of stones, thou dost not wave over them iron.

Moreover, you are to build there an altar to the LORD your God, an altar of stones. You must not use any iron tool on them.
