εἰ σοὶ δοκεῖ
From LSJ
πολλάκις δοκεῖ τὸ φυλάξαι τἀγαθὰ τοῦ κτήσασθαι χαλεπώτερον εἶναι → it often proves harder to keep than to win prosperity | it is often harder for men to keep the good they have, than it was to obtain it
Greek > English (Woodhouse)
if it seems good to you, if you agree, if you are OK with that, if you have no objection, if you please, subject to your approval, with your approval
