¹ tn The description of his heart being “hard” means that he is cruel and fearless. The word for “hard” is the word encountered before for molten or cast metal.

⁶ tn The LXX translates חַשְׁמַל (khashmal) with the word ἤλεκτρον (ēlektron, “electrum”; so NAB), an alloy of silver and gold, perhaps envisioning a comparison to the glow of molten metal.

¹ tn The verb means “to beat out; to flatten,” and the analogy in the next line will use molten metal. From this verb is derived the word for the “firmament” in Gen 1:6-8, that canopy-like pressure area separating water above and water below.

¹ tc Heb “a casting.” The MT reads מַסֵּכָה (massekhah, “a cast thing”) but some mss and Smr add עֵגֶל (ʿegel, “calf”), “a molten calf” or the like (Exod 32:8). Perhaps Moses here omits reference to the calf out of contempt for it.

⁴ sn The word means a “young bull” and need not be translated as “calf” (although “calf” has become the traditional rendering in English). The word could describe an animal three years old. Aaron probably made an inner structure of wood and then, after melting down the gold, plated it. The verb “molten” does not need to imply that the image was solid gold; the word is used in Isa 30:22 for gold plating. So it was a young bull calf that was overlaid with gold, and the gold was fashioned with the stylus.

¹ sn An expanse. In the poetic texts the writers envision, among other things, something rather strong and shiny, no doubt influencing the traditional translation “firmament” (cf. NRSV “dome”). Job 37:18 refers to the skies poured out like a molten mirror. Dan 12:3 and Ezek 1:22 portray it as shiny. The sky or atmosphere may have seemed like a glass dome.
