Arcana Coelestia # 3092
3092. 'And gave him a drink' means introduction. This is clear from the meaning of 'to drink' (potare), an expression meaning almost the same as 'to drink' (bibere). 'To drink' (potare) here however entails a more active role on the part of the one who drinks. 'To drink' (bibere) means to receive, and also to be joined to, see 3069, 3089, so that 'giving a drink to' (facere potare) means imparting the ability to receive, which is the initial stage of the introduction.
Matthew 12:34-39
34
You offspring of vipers, how can you, being evil, speak good things? For out of the abundance of the heart, the mouth speaks.
35
The good man out of his good treasure brings out good things, and the evil man out of his evil treasure brings out evil things.
36
I tell you that every idle word that men speak, they will give account of it in the day of judgment.
37
For by your words you will be justified, and by your words you will be condemned."
38
Then certain of the scribes and Pharisees answered, "Teacher, we want to see a sign from you."
39
But he answered them, "An evil and adulterous generation seeks after a sign, but no sign will be given it but the sign of Jonah the prophet.
