PROVERBS 10:13 KJV "In the lips of him that hath understanding wisdom is found: but a rod [is] for the back of him that is..."
10He that winketh with the eye causeth sorrow: but a prating fool shall fall. 11The mouth of a righteous man is a well of life: but violence covereth the mouth of the wicked. 12Hatred stirreth up strifes: but love covereth all sins. 13In the lips of him that hath understanding wisdom is found: but a rod is for the back of him that is void of understanding. 14Wise men lay up knowledge: but the mouth of the foolish is near destruction. 15The rich man's wealth is his strong city: the destruction of the poor is their poverty. 16The labour of the righteous tendeth to life: the fruit of the wicked to sin.
In the lips of him that hath vnderstanding, wisedome is found: but a rod is for the backe of him that is voyd of vnderstanding.
On the lips of the discerning, wisdom is found, But a rod is for the back of him who lacks understanding.
In the lips of him that hath discernment wisdom is found; But a rod is for the back of him that is void of understanding.
In the lips of an intelligent [man] wisdom is found; but a rod is for the back of him that is void of understanding.
Wisdom is found on the lips of him who has discernment, but a rod is for the back of him who is void of understanding.
In the lips of the intelligent is wisdom found, And a rod [is] for the back of him who is lacking understanding.
10:13 Wisdom - This wisdom shews itself in his speech. A rod - Rebukes from God and men.
I think it is a verse applied to christians who have an understanding of God to be able to correct their kids properly.
