'Acquainted' in the Bible

And so the Lord will make Himself known to Egypt, and the Egyptians will know [heed, honor, and cherish] the Lord in that day. They will even worship with sacrifices [of animals] and offerings [of produce]; they will make a vow to the Lord and fulfill it.

He was despised and rejected by men,A Man of sorrows and pain and acquainted with grief;And like One from whom men hide their facesHe was despised, and we did not appreciate His worth or esteem Him.
