Deuteronomy 15:6 Meaning and Commentary

Deuteronomy 15:6

For the Lord thy God blesseth thee, as he promised thee
He is faithful that has promised, and he always gives the blessing he promises according to the nature of the promise; if absolute, and without conditions, he gives it without respect to any; but if conditional, as the promises of temporal good things to Israel were, he gives according as the condition is performed:

and thou shalt lend unto many nations, but thou shall not borrow;
signifying they should be so rich and increased in goods, and worldly substance, that they should be able to lend to their neighbouring nations round about, but should stand in no need of borrowing of any of them. This is sometimes said of the language of these people, the Hebrew language, that it lends to all, but borrows of none, being an original primitive language; see ( Deuteronomy 28:12 )

and thou shalt reign over many nations:
which was fulfilled in the times of David and Solomon:

but they shall not reign over thee;
that is, as long as they observed the commands of God; otherwise, when they did not, they were carried captive into other countries, and other people reigned over them, as at this day.

Deuteronomy 15:6 In-Context

4 and utterly a needy man and a beggar shall not be among you, that thy Lord God bless thee, in the land which he shall give to thee into possession. (And there shall never be a needy person, or a beggar, among you, and then the Lord thy God shall bless thee, in the land which he shall give to thee for a possession,)

5 If nevertheless thou shalt hear the voice of thy Lord God, and shalt keep all things which he commanded, and which I command today to thee, (if only thou shalt hear the voice of the Lord thy God, and shalt obey all the things which he commanded, and which I command to thee today,)

6 he shall bless thee, as he promised. Thou shalt lend to many folks, and thou shalt not take borrowing of any man; thou shalt be lord of full many nations, and no man shall be lord of thee. (yea, then he shall bless thee, as he promised. Thou shalt lend to many nations, but thou shalt not borrow from anyone; thou shalt be lord of a great many nations, but no one shall be thy lord.)

7 If one of thy brethren that dwell within the gates of thy city, in the land which thy Lord God shall give to thee, cometh to poverty, thou shalt not make hard thine heart, neither thou shalt withdraw thine hand (from him),

8 but thou shalt open it to the poor man, and thou shalt lend him whatso(ever) thou seest him have need to. (but thou shalt open it to the poor, and thou shalt lend to them whatever thou seest that they have need of.)
