'Prime' in the Bible

[The] roar of [the] lion and [the] voice of a lion in its prime, and [the] teeth of [the] young lions are broken.

And [if my head] grows bold, you would hunt me as the lion in its prime; {and you repeat your exploits against me}.

{Proud wild animals} have not trodden it; [the] lion in its prime has not prowled over it.

like when I was in my prime and God trusted me with his secrets!
