[5:15] 1 sn Paul Kruger develops this section as an allegory consisting of a series of metaphors. He suggests that what is at issue is private versus common property. The images of the cistern, well, or fountain are used of a wife (e.g., Song 4:15) because she, like water, satisfies desires. Streams of water in the street would then mean sexual contact with a lewd woman. According to 7:12 she never stays home but is in the streets and is the property of many (P. Kruger, “Promiscuity and Marriage Fidelity? A Note on Prov 5:15-18,” JNSL 13 [1987]: 61-68).
[27:1] 2 tn The form אַל־תִּתְהַלֵּל (’al-tithallel) is the Hitpael jussive negated; it is from the common verb “to praise,” and so in this setting means “to praise oneself” or “to boast.”
[27:1] sn The verse rules out one’s overconfident sense of ability to control the future. No one can presume on the future.
[27:1] 3 sn The word “tomorrow” is a metonymy of subject, meaning what will be done tomorrow, or in the future in general.
[27:1] 4 sn The expression “you do not know” balances the presumption of the first line, reminding the disciple of his ignorance and therefore his need for humility (e.g., Matt 6:34; Luke 12:20; Jas 4:13-16).
