Alexander, as the oldest living brother, had the right not only to the throne but also to Salome, the widow of his deceased brother, who had died childless; and, although she was thirteen years older than him, he married her in accordance with Jewish law.
Aleksander, sebagai yang tertua di antara saudara-saudara yang masih hidup, memiliki hak tidak hanya untuk tahta, tetapi juga untuk Salome, janda almarhum saudaranya, yang telah meninggal tanpa anak; dan, meskipun ia berusia tiga belas tahun lebih tua darinya, dia menikahinya sesuai dengan hukum Yahudi.
