[4:20]  ¹ tn A כּוּר (kur) was not a source of heat but a crucible (“iron-smelting furnace”) in which precious metals were melted down and their impurities burned away (see I. Cornelius, NIDOTTE 2:618-19); cf. NAB “that iron foundry, Egypt.” The term is a metaphor for intense heat. Here it refers to the oppression and suffering Israel endured in Egypt. Since a crucible was used to burn away impurities, it is possible that the metaphor views Egypt as a place of refinement to bring Israel to a place of submission to divine sovereignty.

[4:20]  ² tn Heb “to be his people of inheritance.” The Lord compares his people to valued property inherited from one’s ancestors and passed on to one’s descendants.

[30:18]  ³ tn The Hebrew text uses the infinitive absolute for emphasis, which the translation indicates with “certainly.”

[30:18]  ⁴ tn Heb “to go there to possess it.”
