Ecclesiastes 9:5-10

Yes, the living know they are going to die, but the dead know nothing. They have no further reward; they are completely forgotten. Their loves, their hates, their passions, all died with them. They will never again take part in anything that happens in this world. Go ahead — eat your food and be happy; drink your wine and be cheerful. It's all right with God. Always look happy and cheerful. Enjoy life with the woman you love, as long as you live the useless life that God has given you in this world. Enjoy every useless day of it, because that is all you will get for all your trouble. Work hard at whatever you do, because there will be no action, no thought, no knowledge, no wisdom in the world of the dead — and that is where you are going.
