Jonadab was a very subtle man - And most diabolic advice did he give to his cousin. We talk of the simplicity and excellence of primitive times! "Say not thou what is the cause that the former days were better than these." Take them altogether, we may thank God that they are past, and pray him that they may never return.
Shimeah - Called Shamma (marginal reference), was Jesse‘s third son.
Subtil - literally, wise. The word is generally used in a good sense, but here, and in Job 5:13, it means crafty.
