Didache

But let every one that cometh in the name of the Lord be received; and then when ye have tested him ye shall know him, for ye shall have understanding on the right hand and on the left.

Πᾶς δὲ ὁ ἐρχόμενος ἐν ὀνόματι κυρίου δεχθήτω: ἔπειτα δὲ δοκιμάσαντες αὐτὸν γνώσεσθε, σύνεσιν γὰρ ἕξετε δεξιὰν καὶ ἀριστεράν.

If the comer is a traveler, assist him, so far as ye are able; but he shall not stay with you more than two or three days, if it be necessary.

εἰ μὲν παρόδιός ἐστιν ὁ ἐρχόμενος, βοηθεῖτε αὐτῷ, ὅσον δύνασθε: οὐ μενεῖ δὲ πρὸς ὑμᾶς εἰ μὴ δύο ἡ τρεῖς ἡμέρας, ἑὰν ᾖ ἀνάγκη.
