a.mam denotes becoming dark or obscured, whether of gold losing brightness or of something concealed or overshadowed.

The attested uses chiefly describe obscuring from view: concealed matters in Ezekiel 28:3 and a tree not overshadowed in Ezekiel 31:8. Lamentations 4:1 applies the verb to gold becoming dark.

1. Obscured from view or concealment · dominant

   In Ezekiel 28:3, the Qal perfect plural form occurs in the clause about no hidden thing being concealed; in Ezekiel 31:8, the same Qal perfect plural morphology occurs where the APB says that no cedars “overshadowed it.” Both contexts present something as screened or blocked from view.

2. Becoming dark in appearance · occasional

   In Lamentations 4:1, the Hophal imperfect singular form stands in the opening question about gold: the APB renders, “How has gold become dark?” The clause concerns a visible loss of brightness.

   Lamentations 4:1

In the Anselm Project Bible: The APB presents the contexts with “concealed,” “overshadowed,” and “become dark.” Because it is a whole-verse translation, these expressions indicate the clauses' presentation rather than fixed renderings of the lemma.
