27:3 {b} And thou shalt write upon them all the words of this law, when thou art passed over, that thou mayest go in unto the land which the LORD thy God giveth thee, a land that floweth with milk and honey; as the LORD God of thy fathers hath promised thee.
(b) God would have his law set up in the borders of the land of Canaan, that all that looked on it might know that the land was dedicated to his service.
27:3 This law - The law properly so called, that is, the sum and substance of the precepts or laws of Moses, especially such as were moral, particularly the decalogue. Write it, that thou mayest go in - As the condition of thy entering into the land. For since Canaan is given only by promise, it must be held by obedience.
27:1-10 As soon as they were come into Canaan, they must set up a monument, on which they must write the words of this law. They must set up an altar. The word and prayer must go together. Though they might not, of their own heads, set up any altar besides that at the tabernacle; yet, by the appointment of God, they might, upon special occasion. This altar must be made of unhewn stones, such as they found upon the field. Christ, our Altar, is a stone cut out of the mountain without hands, refused by the builders, as having no form or comeliness, but accepted of God the Father, and made the Head of the corner. In the Old Testament the words of the law are written, with the curse annexed; which would overcome us with horror, if we had not, in the New Testament, an altar erected close by, which gives consolation. Blessed be God, the printed copies of the Scriptures among us, do away the necessity of such methods as were presented to Israel. The end of the gospel ministry is, and the end of preachers ought to be, to make the word of God as plain as possible. Yet, unless the Spirit of God prosper such labours with Divine power, we shall not, even by these means, be made wise unto salvation: for this blessing we should therefore daily and earnestly pray.
