Yea, they opened their mouth wide against me - See the notes at Psalm 22:13.

And said, Aha, aha! - See Psalm 40:15; Psalm 70:3. The language is that which we use when we "detect" another in doing wrong - in doing what he meant to conceal.

Our eye hath seen it - We are not dependent on the reports of others. We have seen it with our own eyes. We have found you out. We cannot be mistaken in regard to it. The reference is to some supposed "detection" of misconduct on the part of David, and the joy and triumph of such a supposed detection.

They opened their mouth wide - Gaped upon me to express their contempt.

And said, Aha, aha, our eye hath seen it - They said, האח האח heach, heach, the last syllable in each word being a protracted strongly guttural sound, marking insult and triumph at the same time. It is the word which we translate Ah, Psalm 35:25.

Yea, they opened their mouth wide against me,.... In laughter, scorn, and derision; see Psalm 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.

Yea, they opened their mouth wide against me, and said, Aha, aha, {q} our eye hath seen it.

(q) They rejoiced as though they had now seen David overthrown.

35:21 Wide - To pour forth whole floods of scoffs and slanders. ha - An expression of joy and triumph. Our eye - What we have long desired and hoped for.

21. On the gesture compare Ps 22:7; and on the expressions of malicious triumph, compare Ps 10:13; 28:3.

35:17-28 Though the people of God are, and study to be, quiet, yet it has been common for their enemies to devise deceitful matters against them. David prays, My soul is in danger, Lord, rescue it; it belongs to thee the Father of spirits, therefore claim thine own; it is thine, save it! Lord, be not far from me, as if I were a stranger. He who exalted the once suffering Redeemer, will appear for all his people: the roaring lion shall not destroy their souls, any more than he could that of Christ, their Surety. They trust their souls in his hands, they are one with him by faith, are precious in his sight, and shall be rescued from destruction, that they may give thanks in heaven.
