I will give thee the worth of it in money - literally, “I will give thee silver, the worth of it.” Money, in our sense of the word, that is to say, coins of definite values, did not yet exist. The first coin known to the Jews was the Persian daric, with which they became acquainted during the captivity. (1 Chronicles 29:7 note).
