'Only, if thou dost diligently hearken to the voice of Jehovah thy God, to observe to do all this command which I am commanding thee to-day,

Only if you carefully listen to the voice of the LORD your God, to observe to do all these commandments which I command you this day.

If only you give ear to the voice of the Lord your God, and take care to keep all these orders which I give you today.

But only if you heed the voice of the Lord your God, and keep to all that he has ordered, that which I am entrusting to you this day, will he bless you, just as he has promised.

This blessing would not fail, if the Israelites would only hearken to the voice of the Lord; "for Jehovah blesseth thee" (by the perfect בּרכך, the blessing is represented not as a possible and future one only, but as one already bestowed according to the counsel of God, and, so far as the commencement was concerned, already fulfilled), "as He hath spoken" (see at Deuteronomy 1:11). "And thou wilt lend on pledge to many nations, but thou thyself wilt not borrow upon pledge." עבט, a denom. verb, from עבוט, a pledge, signifies in Kal to give a pledge for the purpose of borrowing; in Hiphil, to cause a person to give a pledge, or furnish occasion for giving a pledge, i.e., to lend upon pledge. "And thou wilt rule over many nations," etc. Ruling is mentioned here as the result of superiority in wealth (cf. Deuteronomy 28:1 : Schultz).
