Rabbi Yishmael taught: Before Adam, the first man, sinned, the dread of him was set upon every beast, wild animal, and bird; but once he sinned, their dread was set upon him. Before he sinned he would hear the voice [of God] as the speech of a free man, but once he sinned he heard the voice as the speech of a hired man [fearful]. Before he sinned he would hear the voice and stand upon his feet; this is what is written, "And they heard the voice of the LORD God walking about" - Rabbi Abba bar Kahana said: it is not written here "walking" but "walking about," leaping and ascending. But once he sinned, he heard the voice and "the man and his wife hid themselves." Rabbi Eivo said: at that moment his stature was diminished and became a hundred cubits. Before that incident befell David, what is written? (Psalms 27:1) "The LORD is my light and my salvation; whom shall I fear? The LORD is the stronghold of my life; of whom shall I be afraid?" But once that incident befell David, what is written? "And I will come upon him while he is weary and weak-handed, and I will terrify him." Before Solomon sinned he ruled over the demons; this is what is written (Ecclesiastes 2:8), "I made for myself male and female singers and the delights of the sons of men, a chest and chests" [shidah and shidot] - for he ruled over the male demons [shedim] and female demons [shedot]. But once he sinned, he would bring sixty mighty men to guard him; this is what is written (Song of Songs 3:7), "Behold, the bed of Solomon" with sixty mighty men around it. Before Saul sinned, what is written of him? "And Saul took the kingship over Israel, and he fought against all his enemies on every side... and wherever he turned he condemned [yarshia]." What does "yarshia" mean? He triumphed. But once he sinned, what is written? (1 Samuel 28:5) "And Saul saw the camp of the Philistines, and he was afraid, and his heart trembled greatly."
