'Future' in the Bible

Then Hezekiah said to Isaiah, “The word of the Lord which you have spoken is good.” For he thought, “Is it not good, if [at least] there will be peace and security in my lifetime?”

And he made his son go through the fire, and made use of secret arts and signs for reading the future; he gave positions to those who had control of spirits and to wonder-workers; he did much evil in the eyes of the Lord, moving him to wrath.
