Jezekiel 6:10

10 And they shall know that I the Lord have spoken.

Jezekiel 6:10 In-Context

8 When there are of you escaping from the sword among the Gentiles, and when ye are scattered in the countries;
9 then they of you that escape among the nations whither they were carried captive shall remember me; (I have sworn against their heart that goes a-whoring from me, and their eyes that go a-whoring after their practices;) and they shall mourn over themselves for all their abominations.
10 And they shall know that I the Lord have spoken.
11 Thus saith the Lord; Clap with hand, and stamp with foot and say, Aha, aha! for all the abominations of the house of Israel: they shall fall by the sword, and by pestilence, and by famine.
12 He that is near shall fall by the sword; and he that is far off shall die by the pestilence; and he that is in the siege shall be consumed with famine: and I will accomplish mine anger upon them.
