Psalms 35:21

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

[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.
