Ezra 9:14 (KJV)

Now therefore give not your daughters unto their sons, neither take their daughters unto your sons, nor seek their peace or their wealth for ever: that ye may be strong, and eat the good of the land, and leave it for an inheritance to your children for ever.

And after all that is come upon us for our evil deeds, and for our great trespass, seeing that thou our God hast punished us less than our iniquities deserve, and hast given us such deliverance as this;

Should we again break thy commandments, and join in affinity with the people of these abominations? wouldest not thou be angry with us till thou hadst consumed us, so that there should be no remnant nor escaping?

O Lord God of Israel, thou art righteous: for we remain yet escaped, as it is this day: behold, we are before thee in our trespasses: for we cannot stand before thee because of this.
