Do not say, “Why were the old days better than these days?” for it is not wise to ask that.

yet a fool keeps on babbling. No one knows what will happen; who can tell him what will happen in the future?

Divide your merchandise among seven or even eight investments, for you do not know what calamity may happen on earth.

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?”

Just as you do not know the path of the wind, or how the bones form in the womb of a pregnant woman, so you do not know the work of God who makes everything.
