Exodus 30:11 And יהוה spoke to Moses saying, 12 When you take אֶת־ the sum (census) of the Children of Israel, then every man will give a ransom for his soul to ליהוה; that there will be no plague among אֹתָם them after you number אֹתָם them. C-MATS
Question: What is the concern about counting the people of Israel? The Torah teaches that it is forbidden to count יהוה’s people in the ordinary manner, and that when it is necessary to conduct a census, it should be done by having the people contribute items, which would then be counted. In the case of the census in the Wilderness, the people, rich and poor alike, were called upon to contribute half a shekel each, for the construction and upkeep of the Tabernacle. The status of Israel is elevated by its contributions to charitable causes, and this is why they were counted by having the entire nation join in contributing to a sacred cause. Chumash
Question: Why does the Torah forbid counting the people? The evil one has power over numbered things because man looks at the number not יהוה, and pestilence comes upon them, as we find in David’s time. King David took a census of all the people and יהוה punished the nation because of David’s sin. Chumash
Exodus 30:15 The rich will not give more and the poor will not give less than half a shekel, when they give אֶת־ an offering to יהוה to make atonement for your souls. C-MATS
Question: Why did יהוה say this? People differ in their intellect, character, and talents, in the quantity of their material resources and the quality of their spiritual sensitivities. But all are equal in the sight of יהוה and every man is judged fairly according to his deeds and sins. Chumash
