Precept upon Precept is misleading. We have a common misunderstanding that the verses in Isaiah are talking about teaching or admonishment—the primary meanings of the word Precept in modern English. The Hebrew and Latin texts for Isaiah 28:9 are To whom will he, the prophet, teach knowledge? And whom will he make to understand doctrine? Those who are weaned from the milk. Those who are drawn from the breasts. (Hebrews 5:13) 10. For command must be upon command, command upon command; line upon line, line upon line; here a little, there a little, 11. for he will speak to this people with stammering lips and another tongue. (1 Corinthians 14:21) 12. To whom he said, This is the rest with which you may cause the weary to rest, and this is the refreshing, yet they would not listen. 13. But the Word of the LORD* was to them commandment upon commandment, commandment upon commandment, line upon line, line upon line; here a little, there a little; so they could go and fall backward, be broken, snared, and taken.
