3. The consent they cheerfully give to their part of the covenant, v. 5. When the Jews returned out of captivity they renewed their covenant with God (Jer. l. 5), particularly that they would have no more to do with idols, Hos. xiv. 2, 3, 8. Backsliders must thus repent and do their first works. Many of those that were without did at that time join themselves to them, invited by that glorious appearance of God for them, Zech. viii. 23; Esth. viii. 17. And they say, We are the Lord's and call themselves by the name of Jacob; for there was one law, one covenant, for the stranger and for those that were born in the land. And doubtless it looks further yet, to the conversion of the Gentiles, and the multitudes of them who, upon the effusion of the Spirit, after Christ's ascension, should be joined to the Lord and added to the church. These converts are one and another, very many, of different ranks and nations, and all welcome to God, Col. iii. 11. When one does it another shall by his example be invited to do it, and then another; thus the zeal of one may provoke many. (1.) They shall resign themselves to God: not one in the name of the rest, but every one for himself shall say, "I am the Lord's; he has an incontestable right to rule me, and I submit to him, to all his commands, to all his disposal. I am, and will be, his only, his wholly, his for ever, will be for his interests, will be for his praise; living and dying I will be his." (2.) They shall incorporate themselves with the people of God, call themselves by the name of Jacob, forgetting their own people and their fathers' house, and desirous to wear the character and livery of God's family. They shall love all God's people, shall associate with them, give them the right hand of fellowship, espouse their cause, seek the good of the church in general and of all the particular members of it, and be willing to take their lot with them in all conditions. (3.) They shall do this very solemnly. Some of them shall subscribe with their hand unto the Lord, as, for the confirming of a bargain, a man sets his hand to it, and delivers it as his act and deed. The more express we are in our covenanting with God the better, Exod. xxiv. 7; Jos. xxiv. 26, 27; Neh. ix. 38. Fast bind, fast find.
