2 Samuel 13:32

Jonadab was a man of great craft and subtlety, and one that had exact knowledge of Amnon's fact, and of Absalom's temper. By the appointment, or, by the command; Heb. mouth, put for command, Numbers 3:16. From the day; it was resolved from that time in his breast; but the word of command was not then given to others, for that would probably have hindered his design. But all this he seems to have spoken from a probable conjecture, rather than of certain knowledge, as appears by the sequel.
