if only thou diligently hearken unto the voice of Jehovah thy God, to observe to do all this commandment which I command thee 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.

αν μονον επιμελως ακουης την φωνην Κυριου του Θεου σου, δια να προσεχης να καμνης πασας τας εντολας ταυτας, τας οποιας εγω σε προσταζω σημερον.

Only if thou carefully hearken unto the voice of the Lord thy God, to observe to do all these commandments which I command thee this day.
