"Oh, Jerusalem" by Dominique Lapierre and Larry Collins includes a discussion of the threat to "throw the Jews into the sea", including identifying the Palestinian Arab leader who seems to have originated it. I do not have the book handy but if you own it you can find the discussion by using the index. I am sorry, but I do not remember exactly what term points you to the right page, although I do remember finding it from the index a number of years ago.

Got it. Updated.

As a scientist, I always appreciate being cited. :-)

It's in Hebrew,
AHMAD AL-SHUQAYRI FOUNDED THE PLO.
surely said on June 2 , 1967

אם יכבשו הערבים את"
ישראל, אמר, הם יסייעו ליהודים שיישארו בחיים לשוב לארצות מוצאם, 'אבל להערכתי
איש מהם לא יישאר בחיים"

If the Arabs will concur Israel,they will help the Jews to return to their original
motherland, but my estimate there there will be not a living Jew to do it

According to many sources, he also call for "Throwing the Jews into the Sea" ?

Summery in English of the above

it's titled Did Shuqayri Call for "Throwing the Jews into the Sea" ?

Shuqayri, who was noted for his rhetorical skill and vociferous
attacks against Israel in international, Arab, and Palestinian
forums, reached the nadir of his status after the Six-Day War. The
Arab world accused him of contributing to its defeat with his
radical declarations against Israel before the war, which had
resulted in the world favoring Israel. Shuqayri thus served as a
scapegoat for the Arab defeat in the war, a position eagerly seized
upon by his enemies and opponents.

Sa'ad Jum'a, Jordanian prime minister during the Six-Day War
wrote:

My opinion of Shuqayri—objectively—is that he is one of
the direct causes for the catastrophe [the Arab defeat in the
Six-Day War]. He had the appearance and bearings to play a role
perfectly suited to him in the catastrophe of the Arab world and in
Arab disputes, and unfortunately he fulfilled this function with
alacrity and expertise. When the Arab nation and Arab leaders stood
before the bitter facts, after the campaign of humiliation and
shame . . . [and] when a new period dawned. . . Shuqayri no longer
had a place [in it], and he vanished from the stage. Some people
can be likened to a drum—when you strike it, it produces a clamor
and din because of its emptiness.

Shuqayri became famous for supposedly calling on the Arabs "to
throw the Jews into the sea" on the eve of the Six-Day War.
According to Shuqayri, Israel's "spin doctors" exploited this
proclamation in order to prove the threat to Israel's existence and
to expose the Arabs' aggressive intentions. Israel hoped in this
way to justify to international circles that the war it had
launched was one of defense or no-choice.

The claim that on the eve of the Six-Day War Shuqayri called for
throwing the Jews into the sea was picked up not only in the West,
but also by Arab and Palestinian elements that used it against him.
With Arab "confirmation" of this claim, researchers in the West
also began referring to it. According to Mark Tessler, "The PLO's
Ahmad Shuqayri coined a famous phrase asserting that the Arabs
would throw the Jews into the sea."

In Helena Cobban's words:

For his part Shuqayri was remembered in later years,
even by many Palestinians, as 'the man who gave the Palestinians a
bad name by threatening to throw the Jews into the sea.' He himself
always strongly denied that this was, in fact, what he had said on
the eve of the 1967 War. But in many ways, the most significant
thing is that this is the way he was remembered by his
constituency.

As Jordanian historian Samir A. Mutawi wrote:

Nasser's closure of the straits [the Straits of Tiran,
on May 22, 1967] and Shuqayri's bellicose statement—that the time
had come to annihilate the State of Israel and that the Arabs would
throw the Jews into the sea—had alienated world opinion to such an
extent that military activity by Israel would be regarded with
positive favor.

On the other hand, Randolph S. Churchill and Winston S.
Churchill emphasized shortly after the war that Shuqayri's
statement regarding the destruction of those Jews remaining after
the war made no mention of throwing them into the sea:

Israel utilized the first part of his speeches.......in order to show the wrold .....that the arab want to throw the judeans to the sea. Very regretfully , some of the arab leaders said these things.

Of course most of the Arab Leaders rants are about annihilating "Israel" as if you could just annihilate the state and not the people in it.
There's this
"D-Day is approaching. The Arabs have waited 19 years for this and will not flinch from the war of liberation." – Ahmed Shukairy, Chairman of the Palestine Liberation Organization, May 27, 1967
"This is a fight for the homeland – it is either us or the Israelis. There is no middle road. The Jews of Palestine will have to leave. We will facilitate their departure to their former homes. Any of the old Palestine Jewish population who survive may stay, but it is my impression that none of them will survive." – Shukairy, June 1, 1967
"We shall destroy Israel and its inhabitants and as for the survivors – if there are any – the boats are ready to deport them." – Shukairy, June 1, 1967, speaking at a Friday sermon in Jerusalem
