以色列人出埃及地後，第二年二月初一日，耶和華在西奈的曠野、會幕中曉諭摩西說： 「你要按以色列全會眾的家室、宗族、人名的數目計算所有的男丁。 凡以色列中，從二十歲以外，能出去打仗的，你和亞倫要照他們的軍隊數點。 民數記 1:1-3
The people of Israel had left Egypt and were living in the Sinai Desert. Then on the first day of the second month of the second year, when Moses was in the sacred tent the Lord said: I want you and Aaron to find out how many people are in each of Israel’s clans and families. And make a list of all the men 20 years and older who are able to fight in battle. Numbers 1:1-3
