John Gill Commentary Deuteronomy 14:20

"Of all clean birds ye may eat." — Deuteronomy 14:20 (ASV)

But of all clean fowls you may eat .
] Even of all fowls, but those before excepted; Aben Ezra instances in the locust, as being a clean fowl, that might be eaten; and so the Targum of Jonathan is ''every clean locust you may eat;'' see (Leviticus 11:22) .
