Midrasch Tillim on Ps. iv.: "Stand in awe and sin not." Stand in awe and be afraid of your lust, and it will not lead you into sin. And on Ps. xxxvi. "The wicked has said in his heart: Let not the fear of God be before me." That is to say that the malignity natural to man has said that to the wicked.
Misdrasch el Kohelet: "Better is a poor and a wise child than an old and foolish king who cannot foresee the future." The child is virtue, and the king is the malignity of man. It is called king because all the members obey it, and old because it is in the heart of man from infancy to old age, and foolish because it leads man in the way of perdition which he does not foresee.
The same thing is in Misdrasch Tillim.
Bereschist Rabba on Ps. xxxv.: "Lord, all my bones shall bless thee, who deliverest the poor from the tyrant." And is there a greater tyrant than the evil leaven? And on Proverbs xxv., "If thine enemy be hungry, feed him." That is to say, if the evil leaven hunger, give him the bread of wisdom of which speaks Prov. ix., and if he be thirsty, give him the water of which speaks Isaiah lv.
Misdrasch Tillim says the same thing, and that the Scripture in that passage speaking of our enemy, means the evil leaven, and that in giving it that bread and that water, we heap coals of fire on his head.
Misdrasch Kohelet on Ecclesiastes ix. "A great king besieged a little city." This great king is the evil leaven, the great engines with which he surrounds it are temptations, and there has been found a poor wise man who has delivered it, that is to say virtue.
And on Ps. xli. "Blessed is he that considereth the poor."
And on Ps. lxxviii. The spirit goeth and returneth not again, whereof some have taken occasion of error concerning the immortality of the soul; but the sense is that this spirit is the evil leaven, which accompanies man till death, and will not return at the resurrection.
And on Ps. ciii. the same thing.
And on Ps. xvi.
