Isaiah 56:5-6

56:5 I will set up within my temple and my walls a monument

that will be better than sons and daughters.

I will set up a permanent monument for them that will remain.

56:6 As for foreigners who become followers of the Lord and serve him,

who love the name of the Lord and want to be his servants –

all who observe the Sabbath and do not defile it,

and who are faithful to my covenant –
