Thought from Today's Old Testament Passage:
[Proverbs 30] This and the following chapter constitute an appendix to the Book of Proverbs. It is impossible to say who Agur was. In this selection from his writings we have an introduction, in which he affirms the fact of man's little wisdom, and then utters the memorable prayer which reveals his fear of Jehovah and his desire for that balanced life which is one of safety.
From the prayer to the end of the chapter we have his observations on various matters affecting conduct. In this the first section opens with a proverb (verse 10). Then follow descriptions of four evil generations and of "four things" perpetually dissatisfied. The second section opens with a proverb (verse 17), and is followed by four groups of four things. The first four excite wonder, the second four, terror; the third four are little things, but exceeding wise; the final four are stately things. The whole movement ends with a proverb (verses 32,33).
[Proverbs 31] This is the second section of the appendix. There have been many conjectures as to who King Lemuel was, but nothing certainly can be said. It is divided into two parts, the first of which consists of his mother's advice to him.
The second half is a beautiful picture of a virtuous woman, and may be supposed to be King Lemuel's picture of his mother.
