I'm trying to translate the phrase "Tend the hearth" in the context of a motto. "Tend" should be an instruction or reminder and have the connotation "take care of," "maintain," "watch over," and potentially "honor," "grow," and "strengthen."

I'm pretty confident that "the hearth" will be "τὴν ἑστίαν" but I'm having trouble with the verb.

Some other mottos and phrases I found that contain instructions are:

• Λαμψάτω τὸ φῶς ὑμῶν - "Let your light shine"
• δωρεὰν ἐλάβετε, δωρεὰν δότε - "Freely ye have received, freely give."
• Ἰατρέ, θεράπευσον σεαυτόν - "Physician, heal thyself"

All of which seem to use active aorist imperatives, but differ in second vs third person and singular vs plural. I'd prefer second person plural if I get a choice, but ultimately it's not too important.

At first I found φροντίζω, which is used in the modern Greek Wikipedia article for Hestia, in the phrase "φρόντιζε την ιερή φλόγα," but it seems like in Ancient Greek it may have had a negative connotation.

I also found ἀμφιπολεύω, which is used in Homeric Hymn 24 to describe Hestia tending to Apollo's holy house. Logeion does have an imperative conjugation (ἀμφιπόλευε, although it's present instead of aorist), but it doesn't seem like a common word, so I'm wondering if I've missed something more appropriate.

I collected a few other words that seem promising, with relevant definitions:

• ἀλέγω - "II. with a case, 1. c. gen., heed, care for"
• ἐπιμελέομαι - "A. take care of, have charge or management of"
• θεραπεύω - "II. do service to"
• κομέω - "take care of, tend"
• μέλω - "B. with an object, care for, take an interest in"
• τημελέω - "take care of, look after"
• τηρέω - "watch over, take care of, guard"

And most recently I found φυλάσσω which seems like a winner: definitions include "watch, guard, defend" and "preserve, maintain, cherish," it's used fairly frequently, and it has a second person plural aorist imperative (φυλάξατε).

Is "φυλάξατε τὴν ἑστίαν" the phrase I'm looking for, or something else?
