Deuteronomy 28:23

28:23 The ¹  sky ²  above your heads will be bronze and the earth beneath you iron.

Deuteronomy 8:9

8:9 a land where you may eat food ³  in plenty and find no lack of anything, a land whose stones are iron ⁴  and from whose hills you can mine copper.

[28:23]  ¹ tc The MT reads “Your.” The LXX reads “Heaven will be to you.”

[28:23]  ² tn Or “heavens” (also in the following verse). The Hebrew term שָׁמַיִם (shamayim) may be translated “heaven(s)” or “sky” depending on the context.

[8:9]  ³ tn The Hebrew term may refer to “food” in a more general sense (cf. NASB, NCV, NLT) or “bread” in particular (cf. NAB, NIV, NRSV).

[8:9]  ⁴ sn A land whose stones are iron. Since iron deposits are few and far between in Palestine, the reference here is probably to iron ore found in mines as opposed to the meteorite iron more commonly known in that area.
