'Highly' in the Bible

No man in all Israel was as handsome and highly praised as Absalom. From the sole of his foot to the top of his head, he did not have a single flaw.

In those days Ahithophel's advice was considered as valuable as a prophetic revelation. Both David and Absalom highly regarded the advice of Ahithophel.

Now Ahithophel's advice that he provided at that time was being compared to one who inquired of God, so highly regarded was Ahithophel's counsel by both David and Absalom.
