Turn you at my reproof: behold, I will pour out my spirit unto you, I will make known my words unto you. Turn you at my reproof - לתוכחתי lethochachti, at my convincing mode of arguing; attend to my demonstrations. This is properly the meaning of the original word.
I will pour out my spirit unto you - "I wil expresse my mynde unto you;" Coverdale. Loo I shall bryngen to you my Spirit; Old MS. Bible. If you will hear, ye shall have ample instruction.
