And all the people answered together, and said, All that the LORD hath spoken we will do. And Moses returned the words of the people unto the LORD.

And all the people answered together: All that the Lord hath spoken, we will do. And when Moses had related the people's words to the Lord,

And all the people answered together, and said, All that Jehovah has spoken will we do! And Moses brought the words of the people back to Jehovah.

and all the people answer together and say, 'All that Jehovah hath spoken we do;' and Moses returneth the words of the people unto Jehovah.

And all the people, answering together, said, Whatever the Lord has said we will do. And Moses took back to the Lord the words of the people.

And all the people responded together: "Everything that the Lord has spoken, we shall do." And when Moses had related the words of the people to the Lord,

Responderunt autem omnis populus pariter, et dixerunt, Quicquid dixit Jehova faciemus. Et retulit Moses verba populi ad Jehovam.

And all the people answered. We shall see in its proper place why God employed Moses as a messenger to carry backwards and forwards the commands and replies; now he merely relates what all the people answered, viz., that they would be obedient in all things. It was not a part, but the whole of the people who promised this, and the reply was unreserved, declaring that they would do whatsoever God required. Yet soon after they relapsed into their natural mind, and kept not their promise even in the smallest degree. Still we may believe that they spoke without dissembling; but that, although without any intention of deceiving God, they were carried away by a kind of headlong zeal, and deceived themselves. Nor was it the object of Moses to tell them in reproach that they had lied to God, or deceitfully boasted with their lips what they did not feel in their hearts; but, by stating how ready they were to obey, he deprives them hereafter of all pretense of ignorance. Nor is there any doubt that God inclined their minds to this docility, in order to establish the doctrine of His law. Meanwhile, let us learn from their example, that we must not merely obey God's word by some earnest impulse; and that a hasty feeling is of no use, unless it be followed by constant perseverance; and, therefore, let us learn to sift; ourselves well, lest: we rashly promise, without serious self-examination, more, than we are able to perform. Yet we must not forget what. I have already said, that they were all made willing by the secret inspiration of God, in order that they might be witnesses both to themselves and others of the many signs, by which the truth and faithfulness of the heavenly doctrine was then confirmed.

All that the Lord - By this answer the people accepted the covenant. It was the preliminary condition of their complete admission into the state of a royal priesthood.

And all the people answered, etc. - The people, having such gracious advantages laid before them, most cheerfully consented to take God for their portion; as he had graciously promised to take them for his people. Thus a covenant was made, the parties being mutually bound to each other.
Moses returned the words - When the people had on their part consented to the covenant, Moses appears to have gone immediately up to the mountain and related to God the success of his mission; for he was now on the mount, as appears from Exodus 19:14.

And all the people answered together,.... By their heads and representatives, the elders, summoned before Moses, to whom he declared the whole will of God; or this being communicated by them to their respective tribes and families, they were all of one mind; there was not a contradicting voice among them, they all gave the same answer, or all united in returning for answer what follows:
all that the Lord hath spoken we will do; obey his voice in all things he directs unto, or commands to be done, and keep the covenant he should make with them, and observe whatever was required on their parts; which was well spoken, if with the heart, and if, under a consciousness of their own weakness, they had expressed their desire of dependence upon the grace of God to enable them to perform, see Deuteronomy 5:28. The Septuagint version adds, "and we will hear", or be obedient, as in Exodus 24:7,
and Moses returned the words of the people unto the Lord; not for his information, who knew very well what they had said, but for the discharge of his office as a mediator and messenger between God and them: this, according to Jarchi, was on the third day of the month.

And they answered together; all that the Lord hath spoken we will do - Thus accepting the Lord to be to them a God, and giving up themselves to be to him a people.
