The kinim of the third plague, when the dust of the land became lice through all Egypt. In Yeshayahu 51:6 the same entry's 'kein' is read 'like gnats' by some and 'in like manner' by others; the lexicon counts it here, and the row says so.

Lift up your eyes to the heavens, And look upon the earth beneath; For the heavens shall vanish away like smoke, And the earth shall wax old like a garment, And they that dwell therein shall die in like manner; But My salvation shall be for ever, And My favour shall not be abolished.

He spoke, and there came swarms of flies, And gnats in all their borders.
