Thank you. All of that makes it much more clear. I would have thought, however, that with the subject change, and with the switch from μετέσσεται to ἕπεται, that ἐχθρὸς μὲν could be answered by the πᾶσα δ᾽.
Here is the whole of the OBGV selection (thanks to mwh for fixing ἐχθρὸς). I’ve used the TLG version and edited it to match the OBGV instead of typing it out, to avoid further typos. A translation of the rest follows, though the rest seemed more straightforward.
τεθνάμεναι γὰρ καλὸν ἐπὶ προμάχοισι πεσόντα
ἄνδρ’ ἀγαθὸν περὶ ᾗ πατρίδι μαρνάμενον.
τὴν δ’ αὐτοῦ προλιπόντα πόλιν καὶ πίονας ἀγροὺς
πτωχεύειν πάντων ἔστ’ ἀνιηρότατον,
πλαζόμενον σὺν μητρὶ φίλῃ καὶ πατρὶ γέροντι
παισί τε σὺν μικροῖς κουριδίῃ τ’ ἀλόχῳ.
ἐχθρὸς μὲν γὰρ τοῖσι μετέσσεται, οὕς κεν ἵκηται,
χρησμοσύνῃ τ’ εἴκων καὶ στυγερῇ πενίῃ,
αἰσχύνει τε γένος, κατὰ δ’ ἀγλαὸν εἶδος ἐλέγχει,
πᾶσα δ’ ἀτιμία καὶ κακότης ἕπεται.
εἰ δ᾽ οὕτως ἀνδρός τοι ἀλωμένου οὐδεμί’ ὤρη
γίνεται οὔτ’ αἰδὼς οὔτ’ ὀπίσω γένεος,
θυμῷ γῆς περὶ τῆσδε μαχώμεθα καὶ περὶ παίδων
θνήσκωμεν ψυχέων μηκέτι φειδόμενοι.
ὦ νέοι, ἀλλὰ μάχεσθε παρ’ ἀλλήλοισι μένοντες,
μηδὲ φυγῆς αἰσχρῆς ἄρχετε μηδὲ φόβου,
ἀλλὰ μέγαν ποιεῖσθε καὶ ἄλκιμον ἐν φρεσὶ θυμόν,
μηδὲ φιλοψυχεῖτ’ ἀνδράσι μαρνάμενοι·
τοὺς δὲ παλαιοτέρους, ὧν οὐκέτι γούνατ’ ἐλαφρά,
μὴ καταλείποντες φεύγετε, τοὺς γεραιούς·
αἰσχρὸν γὰρ δὴ τοῦτο, μετὰ προμάχοισι πεσόντα
κεῖσθαι πρόσθε νέων ἄνδρα παλαιότερον,
ἤδη λευκὸν ἔχοντα κάρη πολιόν τε γένειον,
θυμὸν ἀποπνείοντ’ ἄλκιμον ἐν κονίῃ,
αἱματόεντ’ αἰδοῖα φίλαις ἐν χερσὶν ἔχοντα—
αἰσχρὰ τάγ’ ὀφθαλμοῖς καὶ νεμεσητὸν ἰδεῖν—
καὶ χρόα γυμνωθέντα· νέοισι δὲ πάντ’ ἐπέοικεν,
ὄφρ’ ἐρατῆς ἥβης ἀγλαὸν ἄνθος ἔχῃ·
ἀνδράσι μὲν θηητὸς ἰδεῖν, ἐρατὸς δὲ γυναιξὶν,
ζωὸς ἐών, καλὸς δ’ ἐν προμάχοισι πεσών.
ἀλλά τις εὖ διαβὰς μενέτω ποσὶν ἀμφοτέροισιν
στηριχθεὶς ἐπὶ γῆς, χεῖλος ὀδοῦσι δακών.
εἰ δ᾽ οὕτως ἀνδρός τοι ἀλωμένου οὐδεμί’ ὤρη
γίνεται οὔτ’ αἰδὼς οὔτ’ ὀπίσω γένεος,
θυμῷ γῆς περὶ τῆσδε μαχώμεθα καὶ περὶ παίδων
θνήσκωμεν ψυχέων μηκέτι φειδόμενοι.
If in this way there is not one concern over a wandering man, nor any regard, nor a family coming after him, let us fight with spirit for this land and die for our children never sparing our lives.
ὦ νέοι, ἀλλὰ μάχεσθε παρ’ ἀλλήλοισι μένοντες,
μηδὲ φυγῆς αἰσχρῆς ἄρχετε μηδὲ φόβου,
ἀλλὰ μέγαν ποιεῖσθε καὶ ἄλκιμον ἐν φρεσὶ θυμόν,
μηδὲ φιλοψυχεῖτ’ ἀνδράσι μαρνάμενοι·
However, young men, fight with each other standing fast, and start neither a shameful flight nor a panic, but make your spirits great and brave in your phrenes, and not hold your lives dear battling with men.
τοὺς δὲ παλαιοτέρους, ὧν οὐκέτι γούνατ’ ἐλαφρά,
μὴ καταλείποντες φεύγετε, τοὺς γεραιούς·
αἰσχρὸν γὰρ δὴ τοῦτο, μετὰ προμάχοισι πεσόντα
κεῖσθαι πρόσθε νέων ἄνδρα παλαιότερον,
Don’t flee, leaving behind the older ones, who no longer have nimble knees, the older generation, for this is really a shame [EDIT: or maybe “ugly”? here and below], for an older man falling in the front lines to lie before the youth,
ἤδη λευκὸν ἔχοντα κάρη πολιόν τε γένειον,
θυμὸν ἀποπνείοντ’ ἄλκιμον ἐν κονίῃ,
αἱματόεντ’ αἰδοῖα φίλαις ἐν χερσὶν ἔχοντα—
αἰσχρὰ τάγ’ ὀφθαλμοῖς καὶ νεμεσητὸν ἰδεῖν—
Already having a white head and gray beard, breathing out his brave spirit in the dust, grasping bloody loins in his own hands – these are shameful things and wrath-provoking to see with the eyes –
καὶ χρόα γυμνωθέντα· νέοισι δὲ πάντ’ ἐπέοικεν,
ὄφρ’ ἐρατῆς ἥβης ἀγλαὸν ἄνθος ἔχῃ·
ἀνδράσι μὲν θηητὸς ἰδεῖν, ἐρατὸς δὲ γυναιξὶν,
ζωὸς ἐών, καλὸς δ’ ἐν προμάχοισι πεσών.
ἀλλά τις εὖ διαβὰς μενέτω ποσὶν ἀμφοτέροισιν
στηριχθεὶς ἐπὶ γῆς, χεῖλος ὀδοῦσι δακών.
and skin stripped bare. But all this is suited to the young, so that the shining bloom of lovely youth can hold. A man is admirable to view for men, lovey for women to view, being alive, but he is noble to see having fallen in the front. But let one stride well and stand fast, both legs planted upon the ground, having bitten his lip with his teeth.
LSJ διαβαίνω: I. intr., stride, walk or stand with legs apart, εὖ διαβάς, of a man planting himself firmly for fighting, Il.12.458, Tyrt.11.21;
