Israel accuses opponent Hamas of trying to back out of the ceasefire agreement "at the last minute", and has therefore not yet formally approved the agreement with Hamas.
There is particularly strong resistance among Prime Minister Benjamin Netanyahu's extreme government colleagues.
But during the early evening, several sources report that all questions have been answered and that the government is ready to approve the agreement.
Aryeh Deri, Knesset member and co-founder of the ultra-orthodox Israeli party Shas, confirms according to Jerusalem Post that this is the case.
Thank God, all disagreements are resolved, he says.
Canceled meeting
Benjamin Netanyahu's government was to meet on Thursday to give the green light for the agreement with Hamas, but the meeting is canceled. It will not be held until this issue is resolved and Hamas accepts the entire agreement, it is said.
According to a statement from the Prime Minister's office, the Palestinian Islamist movement has backed down from parts of the agreement mediated "in an attempt to force concessions at the last minute".
High-ranking Hamas representatives, on the other hand, announced that they stand behind the agreement presented.
There is no basis for Netanyahu's claims, said one of them, Sami Abu Zuhri, to AFP.
While Israel has been in final negotiations, Prime Minister Netanyahu has held talks with leaders of the far-right parties he has built his government with.
"Taking a step back"
These leaders do not want a ceasefire, and Itamar Ben-Gvir, Minister for Internal Security, proudly declared on Tuesday that he had "managed to prevent it" during the past year. Netanyahu has consistently accused Hamas of torpedoing the negotiations.
The government colleagues warned that they may leave the government if a ceasefire becomes a reality.
Ending the war is a step back. We are having discussions with the Prime Minister to get guarantees that the war will continue and are waiting for an answer, says Knesset member Zvi Sukkot from Finance Minister Bezalel Smotrich's ultra-conservative party to the news site Ynet.
The agreement has three parts, where the parties have so far only agreed on the first. At 12:15 on Sunday, all weapons are to be laid down and all violence is to cease for six weeks.
