Psalms 35:21

Yea, they opened their mouth wide against me
In laughter, scorn, and derision; see ( Psalms 22:7 Psalms 22:8 ) ;

[and] said, Aha, aha:
a word expressive of joy; and the doubling it shows the greatness of it;

our eye hath seen [it];
what their heart wished for; namely, the distress of him, whose enemies they were.
