A third major section of the Book of Proverbs begins with 22:17. This is clear from several indicators. The proverbs lengthen out again from the typical one verse couplet that characterizes 10:1-26:16 (cf. chs. 1-9). The phrase "my son"appears again as in chapters 1-9. The reason the writer gave the following proverbs (22:17-21) introduces the first sub-section (22:17-23:11). We read in 22:20 (in the Hebrew text) that a group of 30 sayings will follow.
The emphasis in 22:17-24:34 is on the importance of applying the instruction previously given.
The reason many scholars believe Solomon did not write the 36 sayings of the wise (22:17-24:34) is this. The title, "These also are sayings of the wise [or sages, plural],"in 24:23a suggests several writers rather than one.
"The plur. sagespoints to the existence of a special class of wise men, who were oral teachers or writers. The utterances of these men formed a distinct body of thought, part of which is preserved in the Book of Proverbs . . ."156
The word "also"in 24:23a apparently refers to the similar title in 22:17 suggesting that these sages, not Solomon, wrote the proverbs in 22:17-24:22.
The 36 sayings divide into two groups: "the [30] words of the wise"(22:17), and six more "sayings of the wise"(24:23).
