אֶחָד ehhad
The word ehhad (noun) comes from the verbal root ahhad meaning "to unite." Ehhad is best translated with the word "unit," something that is part of the whole, a unit within a community. In the Hebrew mind everything is, or should be, a part of a unity. There is not one tree but a tree composed of units within the unity-roots, trunk, branches and leaves. A tree is also in unity with the other trees-the forest. A son is a unit within the brotherhood and the family.
