But ye cannot bear them now (αλλ' ου δυνασθε βασταζειν αρτ). The literal sense of βασταζω, to bear, occurs in John 12:6. For the figurative as here see Acts 15:10. The untaught cannot get the full benefit of teaching (1. Corinthians 3:1; Hebrews 5:11-14). The progressive nature of revelation is a necessity.
