sha.mir denotes thorny growth in overgrown land and hard flint-like material in comparisons and engraving.

The dominant usage places the noun in scenes where uncultivated or judged land produces thorny growth; a smaller cluster uses it for something hard, in comparisons involving a forehead or heart and in an engraving clause.

1. Thorny growth on uncultivated land · dominant

   The noun occurs in descriptions of land becoming overgrown or difficult to enter. In Isaiah 5:6 the APB renders a neglected place where “thorn and thornbush will ascend,” while Isaiah 7:23 describes former vine land becoming “briers and thorns” and Isaiah 7:25 describes hills avoided for fear of them. Isaiah 10:17 and Isaiah 27:4 likewise place the term among vegetation consumed by fire.

2. Hard material in comparison or engraving · common

   In Ezekiel 3:9, the absolute noun occurs in the comparison that makes the prophet's forehead like “the hardest flint”; Zechariah 7:12 similarly describes a heart set as flint. In Jeremiah 17:1 it occurs in the engraving clause, where the APB renders it “diamond point” alongside the iron stylus and the inscription on heart and altars.

   Ezekiel 3:9Jeremiah 17:1Zechariah 7:12

In the Anselm Project Bible: Across the land scenes, the APB commonly presents the surrounding vegetation with “thorn,” “thorns,” or “briers and thorns.” In the hard-material contexts it renders the clauses with “flint” and, in Jeremiah 17:1, “diamond point”; These renderings show the verse-level presentation rather than a fixed English equivalent.
