Ezekiel 17:18

This verse gives us the reason of this unhappy enterprise, which is summed up in wilful, presumptuous, and most unparalleled perjury. Zedekiah had given his hand; a solemn confirming of the oath, or covenant, and it implies the voluntary act of Zedekiah in swearing, which makes the perjury so much the fouler. All these things; too bad to be named, and most unbecoming any one that was a beneficiary, and had so much from the bounty of one that was not obliged to do any thing for him.
