Jamieson, Fausset and Brown on Ecclesiastes 10:19

19. Referring to Ec 10:18. Instead of repairing the breaches in the commonwealth (equivalent to "building"), the princes "make a feast for laughter (Ec 10:16), and wine maketh their life glad (Psa 104:15), and (but) money supplieth (answereth their wishes by supplying) all things," that is, they take bribes to support their extravagance; and hence arise the wrongs that are perpetrated (Ec 10:5, 6; 3:16; Is 1:23; 5:23). Maurer takes "all things" of the wrongs to which princes are instigated by "money"; for example, the heavy taxes, which were the occasion of Rehoboam losing ten tribes (1Ki 12:4, &c.).
