אָח Strong’s #251 ahh

And again she bare his brother Abel. And Abel was a keeper of sheep, but Cain was a tiller of the ground.

Genesis 4:2

The original pictographic script of Hebrew used a picture for each letter. This word would have had the picture of an ox head (aleph) representing “strength” and a wall (hhet) representing “protection.” This Hebrew word (ahh) has two meanings. The first is a “hearth,” which was a circle of rocks that enclosed the fire to protect and contain it. The second is “the brother.” The brothers of the family, like the rocks of the hearth, surrounded the family inside camp to protect it from enemies. Both the rocks of the hearth and the brothers of the family are the “strong protectors.”
