And Aaron spoke all the words which the Lord had said to Moses: and he wrought the signs before the people,

and Aaron spoke all the words that Jehovah had spoken to Moses, and did the signs before the eyes of the people.

And Aaron spoke all the words which the LORD had spoken to Moses, and performed the signs in the sight of the people.

and Aaron speaketh all the words which Jehovah hath spoken unto Moses, and doth the signs before the eyes of the people;

And Aaron spoke all the words which the Lord had said to Moses. And he accomplished the signs in the sight of the people,

Et loquutus est Aharon omnia verba quae loquutus fuerat Jehova ad Mosen, fecitque signa coram populo.

Aaron spake all the words - It is likely that Aaron was better acquainted with the Hebrew tongue than his brother, and on this account he became the spokesman. See Clarke on Exodus 4:14 (note).
Did the signs - Turned the rod into a serpent, made the hand leprous, and changed the water into blood. See Clarke on Exodus 4:6 (note) and Exodus 4:8 (note).

And Aaron spake all the words which the Lord had spoken unto Moses,.... As Moses had related to him, being his mouth and spokesman:
and did the signs in the sight of the people; not Aaron, but Moses, and these were the turning of his rod into a serpent, and the serpent into a rod again; putting his hand into and out of his bosom, when it was leprous, and then doing the same when it was well again; and taking water out of the river, and changing it into blood, which he did for the confirmation of his mission.
