Ben-Gvir had long pushed for the death penalty bill to be brought to a Knesset vote, but such a move was previously opposed by Israeli political and security leaders who argued it could complicate efforts to free living Israeli hostages held by Hamas in Gaza.
That is no longer a concern since their return after the start of the Gaza ceasefire last month.
Ben-Gvir was one of just a few Israeli ministers who voted against the Gaza ceasefire deal which aimed to end the war. This saw 20 living hostages sent home in exchange for some 2,000 Palestinian prisoners, including about 250 serving life sentences, many convicted of killing Israelis.
"A dead terrorist does not get released alive," commented Limor Son Har-Melech, a member of Jewish Power, and sponsor of the bill.
In 2003, during the Second Intifada, or Palestinian uprising, a then-pregnant Har-Melech and her husband - who lived in a settlement in the occupied West Bank - were attacked by Palestinian gunmen while in their car. Her husband was killed and she was injured, leading her to give birth by an emergency caesarean section.
She told the Knesset one of her husband's killers went on to be released in a previous exchange deal to bring home an Israeli soldier held captive in Gaza. She said he went on to command a deadly attack on another Israeli and take part in the Hamas-led attacks on 7 October 2023, before he was killed during the Gaza war.
