'Consider' in the Bible

Then I turned to consider wisdom, madness, and folly, for what will the man be like who comes after the king? He will do what has already been done.

for he does not often consider the days of his life because God keeps him occupied with the joy of his heart.

Consider the work of God,for who can straighten outwhat He has made crooked?

In the day of prosperity be joyful, but in the day of adversity, consider: God has made the one as well as the other, so that man cannot discover anything that will come after him.
