2 And yearn like newborn infants for pure, spiritual milk, so that by it you may grow up to salvation,

mental - The word here translated 'mental' has the sense of 'suited to the rational faculties' – the mind in contrast with the body – yet I believe there is allusion to logos, from which it is derived, and I have added 'of the word' to mark this allusion.

KJV
