Jahath was the first and Ziza the second, but Jeush and Beriah did not have many sons; so they were counted as one family with one assignment.
NIV
Jahath was chief and Zizah the second, but Jeush and Beriah had not many sons [not enough for a father's house or clan]; so they were counted together as one father's house.
AMP
And Jahath was the chief, and Zizah the second: but Jeush and Beriah had not many sons; therefore they were in one reckoning, according to their father's house.
KJV
"But how can it rest when the LORD has commanded it, when he has ordered it to attack Ashkelon and the coast?"
NIV
How can it [the sword of the Lord] be quiet when the Lord has given it an assignment to discharge? Against Ashkelon and against the [whole Philistine] seashore He has appointed it.
AMP
How can it be quiet, seeing the LORD hath given it a charge against Ashkelon, and against the sea shore? there hath he appointed it.
KJV
