Isaiah 28:10
10 For precept [must be] upon precept, precept upon precept; line upon line, line upon line; here a little, [and] there a little:

Isaiah 28:13
13 But the word of YHVH was unto them precept upon precept, precept upon precept; line upon line, line upon line; here a little, [and] there a little; that they might go, and fall backward, and be broken, and snared, and taken. (Man with dirtbrush in William Miller's Dream)

Isaiah 28:11
11 For with stammering lips and another tongue will he speak to this people. (Hebrew) Man with the dirtbrush knows the proper interpretation.

and when he appears, men may say: "You are too EARNEST, you do not INTERPRET the SCRIPTURES in the PROPER WAY. Let ME TELL YOU HOW TO TEACH your MESSAGE."

...

It does not become us to DRINK FROM THE FOUNTAIN OF THE VALLEY WHEN THERE IS A FOUNTAIN IN THE MOUNTAIN. Let us leave the LOWER STREAMS; let us come to the HIGHER SPRINGS. If there is a POINT of TRUTH that you do not understand, upon which you do not agree, INVESTIGATE, COMPARE SCRIPTURE WITH SCRIPTURE, SINK THE SHAFT OF TRUTH DOWN DEEP INTO THE MINE OF Elohim's WORD. YOU MUST LAY YOURSELVES AND YOUR OPINIONS ON THE ALTAR OF Elohim, PUT AWAY YOUR PRECONCEIVED IDEAS, AND LET THE SPIRIT OF HEAVEN GUIDE INTO ALL TRUTH.
