'Appropriate' in the Bible

For everything there is an appointed time, and an appropriate time for every activity on earth:

God has made everything fit beautifully in its appropriate time, but he has also placed ignorance in the human heart so that people cannot discover what God has ordained, from the beginning to the end of their lives.

I thought to myself, "God will judge both the righteous and the wicked; for there is an appropriate time for every activity, and there is a time of judgment for every deed.

I have seen personally what is the only beneficial and appropriate course of action for people: to eat and drink, and find enjoyment in all their hard work on earth during the few days of their life which God has given them, for this is their reward.
