Isaiah 56:2-4

New Revised Standard Version, Anglicised Catholic Edition

who keeps the sabbath, not profaning it,
    and refrains from doing any evil.

³ Do not let the foreigner joined to the Lord say,
    ‘The Lord will surely separate me from his people’;
and do not let the eunuch say,
    ‘I am just a dry tree.’

    who choose the things that please me
    and hold fast my covenant,
