There's a season for everything and a time for every matter under the heavens:
References for Ecclesiastes 3:1
a time for giving birth and a time for dying, a time for planting and a time for uprooting what was planted,
a time for killing and a time for healing, a time for tearing down and a time for building up,
a time for crying and a time for laughing, a time for mourning and a time for dancing,
a time for throwing stones and a time for gathering stones, a time for embracing and a time for avoiding embraces,
a time for searching and a time for losing, a time for keeping and a time for throwing away,
a time for tearing and a time for repairing, a time for keeping silent and a time for speaking,
a time for loving and a time for hating, a time for war and a time for peace.
What do workers gain from all their hard work?
References for Ecclesiastes 3:9
I have observed the task that God has given human beings.
God has made everything fitting in its time, but has also placed eternity in their hearts, without enabling them to discover what God has done from beginning to end.
I know that there's nothing better for them but to enjoy themselves and do what's good while they live.
Moreover, this is the gift of God: that all people should eat, drink, and enjoy the results of their hard work.
I know that whatever God does will last forever; it's impossible to add to it or take away from it. God has done this so that people are reverent before him.
References for Ecclesiastes 3:14
Whatever happens has already happened, and whatever will happen has already happened before. And God looks after what is driven away.
