'Form' in the Bible

an instructor of foolish ones, a teacher of babes, having the form of the knowledge and of the truth in the law.

and thanks to God, that ye were servants of the sin, and -- were obedient from the heart to the form of teaching to which ye were delivered up;

nay, but, O man, who art thou that art answering again to God? shall the thing formed say to Him who did form it, Why me didst thou make thus?
