Deuteronomy 8:9

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

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).

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.
