Ezekiel 2:4
For they are impudent children and stiffhearted. I do send thee unto them; and thou shalt say unto them, Thus saith the Lord GOD. For they are impudent children and stiffhearted. I do send thee unto them; and thou shalt say unto them, Thus saith the Lord GOD.
God sends Ezekiel to Israel, a people described as impudent and stiffhearted, defiant and stubborn, rebellious, hardhearted and resistant to God, and He commands the prophet to go to them and speak to them God's own message as the word of the Lord God. The sending is deliberate despite their character, for God charges His messenger to deliver what He gives even to those who are defiant and hardhearted. The commission is not made conditional on reception, but requires Ezekiel to speak whether or not the people choose to listen.
That unconditional charge teaches that God's messengers must faithfully declare what God commands even when their hearers resist the message. The verse belongs to the opening chapters of Ezekiel, the first two chapters, which are to be carefully studied as a lesson for God's workers and workmen. Those chapters show God directing His work and His servants with perfect order even when His workings seem difficult and hard to understand, establishing that the work is His while human agents are to serve under His direction, depend on Him, and not claim control or credit for themselves.
Because the message must be delivered despite the character of the people, the commission warns against hindering workers whom God has sent. The message to a hardhearted people also belongs to a setting of accountability, and is to be studied alongside Ezekiel 9 and Revelation 5 in connection with God's scrutiny and judgment of wrongdoing.
