Some others of Ḥiwi's views are preserved in Ibn Ezra's commentary on the Pentateuch. The passing of the Israelites through the Red Sea Ḥiwi explained by the natural phenomenon of the ebb-tide; and the words "the skin of his [Moses'] face shone" ("ḳaran," literally, "cast horns" or "rays"; Exodus xxxiv. 29) he explained as referring to the dryness of his skin in consequence of long fasting (see Ibn Ezra on the passage in Exodus).
The passage discusses how Ḥiwi interpreted certain biblical events, specifically the Israelites crossing the Red Sea and the phrase about Moses' face. Ibn Ezra's commentary provides context for these interpretations.
