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.
Silver
'Silver' signifies spiritual good or truth from a celestial origin. It also represents the truth of faith, or the truth acquired from self-hood, or proprium. 'Silver' means scientific truth. In Genesis 20:16, it signifies rational truth. 'A piece of silver' signifies a truth, or a knowledge of truth. In the internal sense of the Word, it signifies truth, but also falsity.
