פּירוש אויף דברים 14:5

ואקו AND THE אקו — This is rendered in the Targum by יעלא, the same term as the Hebrew יעל in the expression יעלי סלע (Job 39:1). This is what is called in German 'Steinbock'.

איל, “the hart, etc;” [our author proceeds to translate the names of these seven species into medieval French, something of little use my readers. Ed.] In plain English, permitted species of mammals are: ox, sheep, goat; deer, gazelle, roebuck, wild goat, ibex, antelope and mountain sheep plus unnamed species (if there are such) displaying the identification marks listed by the Torah.

The meanings of the terms up till the gazelle and the deer are commonly known; the remaining five terms require the Tradition [Sa’adya Gaon on this verse].

ותאו — This is rendered in the Targum by תורבלא which is the same as תור יער, the ox of the forest (wild ox), for בלא means “forest״ in the Aramaic language.
