Ecclesiastes 5:6

5:6 Do not let your mouth cause you to sin,

and do not tell the priest, “It was a mistake!”

Why make God angry at you

so that he would destroy the work of your hands?”

Ecclesiastes 9:10

9:10 Whatever you find to do with your hands,

do it with all your might,

because there is neither work nor planning nor knowledge nor wisdom in the grave,

the place where you will eventually go.
