Pound
Pound does not correctly represent the Hebrew maneh, which was more than a pound (see Maneh). The litra of Joh 12:3 and 19:39 is the Roman pound (libra) of 4,950 grains, which is less than a pound troy, being about 10 1/3 oz. In a monetary sense (its use in Lu 19:13-25) it is the mna, or maneh, which was either of silver or gold, the former, which is probably the one referred to by Luke, being equal to 6,17 British pounds, or about $33 (in 1915); the latter 102,10 British pounds or $510 (in 1915).
See Weights and Measures.
Figurative: "Pound," like "talent," is used in the New Testament for intellectual gifts and spiritual endowments, as in the passage given above.
