There's a lot of confusion and contradiction in the recent back and forth between Netanyahu and Blinken on restrictions of weapons shipments to Israel. Biden has denied that he is withholding weapons and, in fact, is pushing against some in his own party:

Meanwhile as US claims that Israel supports the ceasefire deal that is being negotiated Netanyahu pledges to “finish the job”.
