Deuteronomy 33:22

Deu 33:22 And of Dan he said, Dan [is] a lion’s whelp: he shall leap from Bashan.

Ver. 22. He shall leap from Bashan, ] i.e., He shall suddenly set upon his enemies; as Ahithophel counselled Absalom, 2Sa 17:1-2 and this is called "good counsel"; 2Sa 17:14 and as Caesar served Pompey,

“ … Caesar in omnia praeceps,

Nil actum credens, dum quid superesset agendum,

Fertur atro … ” - Lucan.
