¹ tc The consonants of the Hebrew text of this verse are similar to the consonants in v. 19. The LXX has a much longer reading: “Like vinegar is bad for a wound, so a pain that afflicts the body afflicts the heart. Like a moth in a garment, and a worm in wood, so the pain of a man wounds the heart” (NRSV follows much of the LXX reading; NAB follows only the second sentence of the LXX reading). The idea that v. 20 is a dittogram is not very convincing; and the Greek version is too far removed to be of help in the matter.

² tn The second simile mentions pouring vinegar on soda. The LXX has “scab,” but that does not fit as a sensitive thing. The reference is to sodium carbonate (natural in Egypt) which can be neutralized with vinegar.

³ sn It is inappropriate and counterproductive to sing songs to a heavy heart. One needs to be sensitive to others (e.g., 1 Sam 19:9).

⁴ tn The subject matter is the vexation produced by a fool. The term כַּעַס (ca’as) means “vexation” (ASV); provocation” (NAB, NASB, NIV, NRSV); “anger” (KJV “wrath”) and usually refers to undeserved treatment. Cf. NLT “the resentment caused by a fool.”

sn The same noun is used in 1 Sam 1:6, 16 for the “provocation” given to Hannah by Peninnah for being barren.

⁵ sn The contrast is made between dealing with the vexation of a fool and physical labor (moving stones and sand). More tiring is the vexation of a fool, for the mental and emotional effort it takes to deal with it is more draining than physical labor. It is, in the sense of this passage, almost unbearable.
