This feast he is planning should have celebrated rather than initiated his campaign for the throne. Rather than having this feast as a kick-off party, Adonijah should have been having this feast once the throne was secured. We will see later in the chapter that Adonijah is quickly thwarted in his attempt to be King. This teaches us today to:
“They who feast when they should fight are likely to end their mirth with sorrow.” -Maclaren.
