Ha'azinu - R'vi'i
We Are Not Amused
"God was not amused by this, so He 'hid His face' from them so they'd see what life would be like without Him. They're a fickle people and they will frequently waver. They've 'cheated on' God with other non-gods before. He can do the same to them, by favoring a 'non-nation.'
“When God gets riled up, His anger will consume the land. The Jews will suffer repeated troubles, like a barrage of arrows. God was ready to annihilate the Jews once, but He refrained so that His Name would not be desecrated among the nations, who would credit their idols for 'overpowering' God. (As if!) These nations are foolish."
