'Verbally' in the Bible

I praise and appreciate you because you remember me in everything and you firmly hold to the traditions [the substance of my instructions], just as I have passed them on to you.

For it would have been better for them not to have [personally] known the way of righteousness, than to have known it and then to have turned back from the holy commandment [verbally] handed on to them.

Beloved, while I was making every effort to write you about our common salvation, I was compelled to write to you [urgently] appealing that you fight strenuously for [the defense of] the faith which was once for all handed down to the saints [the faith that is the sum of Christian belief that was given verbally to believers].
