A bekah for every man, that is, half a shekel, after the shekel of the sanctuary, for every one that went to be numbered, from twenty years old and upward, for six hundred thousand and three thousand and five hundred and fifty men. A bekah for every man - The Hebrew word בקי beka, from בקי baka, to divide, separate into two, seems to signify, not a particular coin, but a shekel broken or cut in two; so, anciently, our farthing was a penny divided in the midst and then subdivided, so that each division contained the fourth part of the penny; hence its name fourthing or fourthling, since corrupted into farthing.
There appear to be three particular reasons why much riches should be employed in the construction of the tabernacle, etc.
1. To impress the people's minds with the glory and dignity of the Divine Majesty, and the importance of his service.
2. To take out of their hands the occasion of covetousness; for as they brought much spoils out of Egypt, and could have little if any use for gold and silver in the wilderness, where it does not appear that they had much intercourse with any other people, and were miraculously supported, so that they did not need their riches, it was right to employ that in the worship of God which otherwise might have engendered that love which is the root of all evil.
3. To prevent pride and vainglory, by leading them to give up to the Divine service even the ornaments of their persons, which would have had too direct a tendency to divert their minds from better things. Thus God's worship was rendered august and respectable, incitements to sin and low desires removed, and the people instructed to consider nothing valuable, but as far as it might be employed to the glory and in the service of God.
