Proverbs 22:6 Train up a child in the way he should go [and in keeping with his individual gift or bent], and when he is old he will not depart from it.
IITimothy 4:3-4 For the time is coming when [people] will not tolerate (endure) sound and wholesome instruction, but, having ears itching [for something pleasing and gratifying], they will gather to themselves one teacher after another to a considerable number, chosen to satisfy their own liking and to foster the errors they hold, and will turn aside from hearing the truth and wander off into myths and man-made fictions.
