As mãos de Moisés, porém, ficaram cansadas; por isso tomaram uma pedra, e a puseram debaixo dele, e ele sentou-se nela; Arão e Hur sustentavam-lhe as mãos, um de um lado e o outro do outro; assim ficaram as suas mãos firmes até o pôr do sol.
Targum Jonathan on Exodus
And the hands of Mosheh were heavy, because the conflict was prolonged till the morrow, and the deliverance of Israel was not prepared on that day; and he could not hold them up in prayer; on which account he would have afflicted his soul. And they took a stone, and placed it under him, and he sat upon it; and Aharon and Hur supported his hand, this the one, and that the other; and his hands were outstretched with firmness, (or, fidelity,) in prayer and fasting, until the going down of the sun.
Targum Jerusalem
And the hands of Mosheh were lifted up in prayer.
