Hebrew

hwy - to become, to lie (HALOT 241)

The presence of hāwā in the Biblical corpus is marginal and may be partly due to Aramaic influence (Wagner 1966:45).

PS
*hwy - to be (Kogan 2015:399)
As pointed out by J. Tropper (1993a:280), “in dieser Bed. und mit w als zweitem Radikal ausschliesslich aram.” The Hebrew form with y (hāyā, HALOT 241) is probably an innovation.
