za.rach describes the sun or light coming into view, and in one context a bodily affliction breaking out.

The verb most often marks the sun’s arrival or shining at morning and its effects in the scene. It also describes light or the LORD appearing over people, while 2 Chronicles 26:19 uses it for leprosy breaking out on Uzziah’s forehead.

1. The sun coming up or shining · dominant

   This is shown in clauses concerning the sun at morning: in 2 Kings 3:22 the APB renders that “the sun shone on the water,” and in Judges 9:33 it renders “as soon as the sun rises.” Ecclesiastes 1:5 places the form in the repeated movement of the sun, while Job 9:7 describes a command under which the sun “does not rise.”

   2 Kings 3:22Ecclesiastes 1:5Job 9:7Jonah 4:8Judges 9:33Psalm 104:22
2. Light or divine glory appearing · common

   The term is used where light emerges in darkness or where the LORD is said to appear upon a people. In Isaiah 58:10 the APB renders that “your light will rise in darkness,” while Isaiah 60:1 and Isaiah 60:2 describe the LORD’s glory or the LORD rising upon the addressee; Deuteronomy 33:2 similarly says that the LORD “dawned from Seir upon them.”

   Deuteronomy 33:2Isaiah 58:10Isaiah 60:1Isaiah 60:2Psalm 112:4
3. A visible affliction breaking out · rare

   In 2 Chronicles 26:19, the Qal perfect feminine singular occurs in the clause that the APB renders “leprosy broke out on his forehead.” This shows an appearance into view rather than the sunrise setting found in the larger group of occurrences.

   2 Chronicles 26:19

In the Anselm Project Bible: The APB presents the term with “shone,” “rises,” “rose,” “dawned,” and “light will rise,” according to the surrounding clause. In 2 Chronicles 26:19 it instead renders the clause “leprosy broke out”.
