ga.ah describes rising or growing upward, including rising water, vegetation, and the LORD's rise in song.

The attested uses chiefly describe upward movement or growth: water rises to swimming depth, a reed rises in a swamp, and something rises like a lion. In the Exodus song, the same form declares that the LORD has risen up as the horse and rider are cast into the sea.

1. Rising or growing upward · dominant

   In Ezekiel 47:5, the Qal perfect plural form occurs where the water has risen to swimming depth; in Job 8:11, the Qal imperfect asks whether a reed can rise where there is no swamp. Job 10:16 uses the Qal imperfect in the statement that it rises like a lion.

2. The LORD's rise proclaimed in song · common

   Exodus 15:1 and Exodus 15:21 repeat the Qal infinitive absolute in the sung declaration that the LORD has risen up, followed by the horse and rider being cast into the sea.

In the Anselm Project Bible: The APB uses “has risen up” in the Exodus song, “had risen” for the water in Ezekiel 47:5, and “rises” or “rise up” in Job. These renderings confirm the clauses' upward-movement imagery without establishing finer distinctions.
