He who has no experience knows few things. But he who has traveled increases cleverness.
DRC34:11
He that hath no experience, knoweth little: and he that hath been experienced in many things, multiplieth prudence. He that hath not been tried, what manner of things doth he know? he that hath been surprised, shall abound with subtlety.
LXXE34:11
Who hath been tried thereby, and found perfect? then let him glory. Who might offend, and hath not offended? or done evil, and hath not done it? His goods shall be established, and the congregation shall declare his alms.
