Noam Sheizaf, at +972, provides a useful list of who voted for (47) and against (38) the new boycott law, as well as who was not present for the vote or abstained from voting.
Those not present included the leading ministers in the government:
Foreign Minister Lieberman (Yisrael Beitenu)
Defense Minister Barak (Atzmaut - split off from Labor)
Prime Minister Netanyahu (Likud)
Education Minister Gideon Sa'ar (Likud)
Internal Security Minister Yitzhak Aharonovitch (Yisrael Beitenu)
It's quite remarkable that they weren't even present for the vote. Sheizaf's comment: "Many of the votes were those of backbenchers, and it seems that the leading ministers preferred not to be present at the vote, once it was clear that the law was going to pass. The three most important ministers in the government–Prime Minister Netanyahu, Defense Minister Ehud Barak and Foreign Minister Avigdor Lieberman—chose not to attend the vote. Some leadership Israel has."
