Midrash su Deuteronomio 28:62

R. Joshua b. Chanina based his lecture on the following passage (Deut. 28, 62) And it shall come to pass that as the Lord rejoiced over you to do you good, and to multiply you, so will the Lord rejoice over you to bring you to nought, and to destroy you. Let us see. Does the Holy One, praised be He! indeed rejoice over the downfall of the wicked? Behold, it is written (II Chr. 20, 21) As they went out before the armed array, and said, Give thanks unto the Lord; for unto everlasting endureth His kindness. Whereupon R. Jochanan said: "Why are the words for he is good, not inserted here? Because the Holy One, praised be He! rejoices not in the downfall of the wicked." And R. Jochanan said again: "What is the meaning of the passage (Ex. 14, 20) And the one came not unto the other all the night? This means that the angels of Heaven wanted to sing the usual song, when the Holy One, praised be He! said unto them: 'My creatures are drowning in the sea, and you want to sing songs!' " [Hence God rejoiceth not in such cases]. Said R. Jose b. Chanina: "He Himself does not rejoice over it, but He causeth others to rejoice over it. This could be proved by the above Passage, which is written Yassiss (He will make rejoice other), and it is not written, Yassuss (He Himself will rejoice)."
