then I saw all the work of God, that man can't find out the work that is done under the sun, because however much a man labors to seek it out, yet he won't find it. Yes even though a wise man thinks he can comprehend it, he won't be able to find it.

When you make a promise to God, don't fail to keep it, since he isn't pleased with fools. Keep what you promise

Don't be in a hurry to leave him, and don't persist in evil, for he does whatever he pleases.

Whoever keeps staring at the wind won't sow; whoever daydreams won't reap.

Sow your seed in the morning, and don't stop working until evening, since you don't know which of your endeavors will do well, whether this one or that, or even if both will do equally well.

Don’t be excessively righteous, and don’t be overly wise. Why should you destroy yourself?

Don’t be excessively wicked, and don’t be foolish. Why should you die before your time?

Just as you don’t know the path of the wind,
or how bones develop in the womb of a pregnant woman,
so you don’t know the work of God who makes everything.

That which is crooked can't be made straight; and that which is lacking can't be counted.

Whatever my eyes desired, I didn't keep from them. I didn't withhold my heart from any joy, for my heart rejoiced because of all my labor, and this was my portion from all my labor.

Don't be rash with your mouth, and don't let your heart be hasty to utter anything before God; for God is in heaven, and you on earth. Therefore let your words be few.

Don't allow your mouth to lead you into sin. Don't protest before the messenger that this was a mistake. Why should God be angry at your voice, and destroy the work of your hands?

Don't curse the king, no, not in your thoughts; and don't curse the rich in your bedroom: for a bird of the sky may carry your voice, and that which has wings may tell the matter.
