| Gill's Exposition of the Entire Bible By number and by weight of everyone,.... They were delivered in by tale and weight, which exactly agreed to the number and weight in which they received them: and all the weight was written at that time; an account was taken in writing, and laid up, that it might not only be known hereafter what freewill offerings had been made in Babylon, but that it might be a voucher for the fidelity and integrity of those that brought them, should it ever be called in question.

Matthew Henry's Concise Commentary8:31-36 Enemies laid wait for the Jews, but God protected them. Even the common perils of journeys, call us to go out with prayer, and to return with praise and thanksgiving. But what shall we render when the Lord has led us safely through the pilgrimage of life, through the gloomy vale of death, out of the reach of all our enemies, into everlasting happiness! Among their sacrifices they had a sin-offering. The atonement sweetens and secures every mercy to us, which will not be truly comfortable, unless sin be taken away, and our peace made with God. Then had the church rest. The expressions here used, direct us to the deliverance of sinners from spiritual bondage, and their pilgrimage to the heavenly Jerusalem, under the care and protection of their God and Saviour. |
