אֶבֶן Strong’s #68 ehven

And if thou make me an altar of stone, thou shalt not build it of hewn stones; for if thou lift up thy tool upon it, thou hast polluted it.

Exodus 20:25

In the land of Israel stones were a common building material. The Hebrew word even (stone) is related to several other words, all related to “building.” Banah (Strongs #1129) is a verb meaning to build. Bohen (Strongs #931) is “the thumb,” considered to be the builder, as the thumb is necessary for doing any work. Ben (Strongs #1121) is the Hebrew word “son,” the building stones of the family.
