At the beginning of Parashat Bemidbar, God asks Moses to “take a census of the whole Israelite community”. Those that are being counted are “every male…from the age of twenty years up, all those in Israel who are able to bear arms.” So, it's only those adult males who can serve in the army. Everyone else, just doesn’t count?
Hello?? I was there! I left Egypt! And the person next to me… that might not be able to fight in battle, they left Egypt too! And what about the children, and the teenagers, and how about the elderly, and how about those that have disabilities? They dreamed about living to see the Land of Israel, too !
Can you imagine the disappointment that some felt when some were counted, and others were pushed aside?
