'Understandeth' in the Bible

Who is the wise man? and he understandeth this, And he to whom the mouth of Jehovah spake? And he doth declare it, For what hath the land perished? It hath been burnt up as a wilderness, Without any passing through.

But let him that glorieth glory in this, that he understandeth and knoweth me, that I am the LORD which exercise lovingkindness, judgment, and righteousness, in the earth: for in these things I delight, saith the LORD.
