Kiss the son, lest he be angry, and you perish in the way, for his wrath is quickly kindled. Blessed are all who take refuge in him. Rav and Rav Acha said, "Kiss the son of the Torah," as it says, "Come, eat of my bread and drink of the wine I have mixed. Leave your simple ways, and live, and walk in the way of insight." And do not think that I need many sparks, but rather I infer and destroy the world with one spark.
"When his anger flares up in a moment, the king's fury is as deadly as the grave. It is a parable of a king who became angry with the people of his kingdom. The people went and appeased the king's son, who then appeased his father. Once the king was appeased by his son, the people went to sing praises to the king. The king said to them, 'You are singing praises only because my son appeased me. Had he not done so, you would have lost your kingdom.' Similarly, the nations of the world wish to sing praises to God, as it is said, 'Clap your hands, all you nations' (Psalms 47:2). God says to them, 'You only want to sing praises because Israel is praying for you. If not for them, you would not even exist for one moment, as it is said, "Rejoice, O nations, with His people" (Deuteronomy 32:43).' Another explanation of the verse, 'When his anger flares up in a moment,' is that when a mortal king becomes angry, he is not willing to be appeased. But God is not like that. Even when He is angry, it is with a purpose, as it is said, 'When his anger flares up in a moment.' Fortunate are those who trust in Him, which refers to Israel, who trust in God at all times so that His anger will not flare up against them."
