Rashi on Deuteronomy 14:5/רש"י על דברים י״ד:ה׳

1ואקו 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'.

2ותאו — 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.
