The Knesset plenum is expected to pass the Sheshinski committee's proposals into law today, increasing the government's take from oil and gas exploitation.
The ruling coalition is mustering its strength to repel dozens of concessions that would benefit the gas companies. The concessions were proposed by Israel Beiteinu MKs.
Meanwhile, National Infrastructure Minister Uzi Landau demanded Monday that the vote be postponed because he wanted to change two clauses that had already been approved last week.
Finance Minister Yuval Steinitz agreed to one of his demands, which was to delete the clause mandating that the Infrastructure Ministry's oil and gas official give the Tax Authority data about oil and gas reserves.
Labor MK Shelly Yachimovich called it "opportunism."
On Monday, Landau had tried to bring the bill back to the Finance Committee to have the whole thing revised, but his proposed revisions had been discussed a week earlier and were rejected.
As a result, he is threatening to object to the bill in the plenum today. It is unusual for a minister to object to a government bill.
Landau objects that the bill would give some of his ministry's authority to the Finance Ministry.
