Deuteronomy 23:20-21

23:20 You may lend with interest to a foreigner, but not to your fellow Israelite; if you keep this command the Lord your God will bless you in all you undertake in the land you are about to enter to possess. 23:21 When you make a vow to the Lord your God you must not delay in fulfilling it, for otherwise he ¹  will surely ²  hold you accountable as a sinner. ³ 

[23:21]  ¹ tn Heb “the Lord your God.” The pronoun has been used in the translation for stylistic reasons to avoid redundancy.

[23:21]  ² tn The Hebrew text uses the infinitive absolute for emphasis, which is reflected in the translation by “surely.”

[23:21]  ³ tn Heb “and it will be a sin to you”; NIV, NCV, NLT “be guilty of sin.”
