Exodus 32:27 Meaning and Commentary

Exodus 32:27

And he said unto them, thus saith the Lord God of Israel,
&c.] The following orders are given by Moses, not of himself the chief magistrate, and as the effect of heat and passion, but there were from the Lord, who was Israel's God and King; he had them expressly from him, or by an impulse on his spirit, or in such a way and manner that he knew it was of God, and this was his will:

put every man his sword by his side;
girt there, ready to be drawn upon order:

and go in and out from gate to gate throughout the camp;
not into the tents, where good men might be bemoaning the sin committed, but throughout the streets, where many were loitering, it being a holy day with the idolaters:

and slay every man his brother, and every man his companion, and
every man his neighbour;
who were idolaters; none were to be spared on account of relation, friendship, and acquaintance.

Exodus 32:27 In-Context

25 And when Moses saw that the people was scattered, —for Aaron scattered them a rejoicing to their enemies, —
26 then stood Moses at the gate of the camp, and said, Who is on the Lord's side? let him come to me. Then all the sons of Levi came to him.
27 And he says to them, Thus saith the Lord God of Israel, Put every one his sword on his thigh, and go through and return from gate to gate through the camp, and slay every one his brother, and every one his neighbour, and every one him that is nearest to him.
28 And the sons of Levi did as Moses spoke to them, and there fell of the people in that day to the three thousand men.
29 And Moses said to them, Ye have filled your hands this day to the Lord each one on his son or on his brother, so that blessing should be given to you.
