Their quiver - See Jeremiah 4:29, note.

Their quiver is an open sepulcher - They are such exact archers as never to miss their mark; every arrow is sure to slay one man.

Their quiver is an open sepulchre,.... The Chaldeans used bows and arrows in fighting; and the quiver is a case for arrows; and the phrase denotes, that their arrows would do great execution, and be very mortal; so that a quiver of them would be as devouring as an open grave, into which many dead are cast. The Septuagint and Arabic versions have not this clause; and the Syriac version renders it, "whose throats are as open sepulchres"; see Romans 3:13,

they are all mighty men; strong in body, of bold and courageous spirits, expert in war, and ever victorious; so that there was no hope of being delivered out of their hands.

Their quiver is as an {p} open sepulchre, they are all mighty men.

(p) Who will kill many with their arrows.

16. open sepulchre-(Compare Ps 5:9). Their quiver is all-devouring, as the grave opened to receive the dead: as many as are the arrows, so many are the deaths.

5:10-18 Multitudes are ruined by believing that God will not be so strict as his word says he will; by this artifice Satan undid mankind. Sinners are not willing to own any thing to be God's word, that tends to part them from, or to disquiet them in, their sins. Mocking and misusing the Lord's messengers, filled the measure of their iniquity. God can bring trouble upon us from places and causes very remote. He has mercy in store for his people, therefore will set bounds to this desolating judgment. Let us not overlook the nevertheless, ver. 18. This is the Lord's covenant with Israel. He thereby proclaims his holiness, and his utter displeasure against sin while sparing the sinner, Ps 89:30-35.
