Deuteronomy 4:26

4:26 I invoke heaven and earth as witnesses against you ¹  today that you will surely and swiftly be removed ²  from the very land you are about to cross the Jordan to possess. You will not last long there because you will surely be ³  annihilated.

Deuteronomy 30:18

30:18 I declare to you this very day that you will certainly ⁴  perish! You will not extend your time in the land you are crossing the Jordan to possess. ⁵ 

[4:26]  ¹ sn I invoke heaven and earth as witnesses against you. This stock formula introduces what is known form-critically as a רִיב (riv) or controversy pattern. It is commonly used in the ancient Near Eastern world in legal contexts and in the OT as a forensic or judicial device to draw attention to Israel’s violation of the Lord’s covenant with them (see Deut 30:19; Isa 1:2; 3:13; Jer 2:9). Since court proceedings required the testimony of witnesses, the Lord here summons heaven and earth (that is, all creation) to testify to his faithfulness, Israel’s disobedience, and the threat of judgment.

[4:26]  ² tn Or “be destroyed”; KJV “utterly perish”; NLT “will quickly disappear”; CEV “you won’t have long to live.”

[4:26]  ³ tn Or “be completely” (so NCV, TEV). It is not certain here if the infinitive absolute indicates the certainty of the following action (cf. NIV) or its degree.

[30:18]  ⁴ tn The Hebrew text uses the infinitive absolute for emphasis, which the translation indicates with “certainly.”

[30:18]  ⁵ tn Heb “to go there to possess it.”
