The 273 Excess Firstborn Are Redeemed with Silver

The firstborn outnumber the stated Levite total by 273, so those 273 are redeemed at five sanctuary shekels each. The arithmetic is exact: 273 × 5 = 1,365 shekels, the amount Moses collects and gives to Aaron and his sons.\ \ Where Scripture takes it next: Numbers 18:15–16 later gives five shekels as the firstborn redemption valuation from one month old. The one-time wilderness accounting and the later standing law share the same amount.\ \ Why it matters: the chapter moves from corporate substitution to individual redemption for the unmatched remainder. Nothing is hand-waved away; the surplus is counted and accounted for.\ \ Evidence boundary: a shekel here is a weight standard, not a modern coin with a fixed dollar value. Modern-money conversions are approximations and belong in Deep Study, not in the basic explanation.
