Eladad and Begin met again in British-ruled Mandatory Palestine, where Scheib was already a leader of the Lehi underground and Begin would soon command the Irgun.
The Lehi was at that point waging a violent struggle for freedom from British rule and the Irgun would, under Begin, soon join the revolt in hopes of turning Palestine into a Jewish state.

Scheib adopted several aliases while living underground, including "Sambatyon" and "Eldad".
He worked in 1942 directly with Lehi founder Avraham Stern.
After Stern's killing by the British, Eldad became one of a triumvirate of Lehi commanders, working together with Natan Yellin-Mor and future prime minister Yitzhak Shamir.
Yellin-Mor was the diplomatic "foreign minister," Shamir the operations man, and Eldad the ideologue.
For the next six years Eldad wrote articles for various underground newspapers, some of which he edited.
Eldad also wrote some of the speeches delivered in court by Lehi defendants.

Eldad was arrested by the British when trying to flee from a Tel Aviv apartment; he was injured in a fall from a water pipe, and imprisoned in Jerusalem in a body cast.
He continued his political and philosophical writing from Cell 18 of the hospital ward at the Jerusalem Central Prison.
Eventually, in June 1946, Eldad healed enough to escape while on a visit in a dentist's clinic, from which several Lehi fighters spirited him away.
