one's best
Kein Zweifel, mein Lehnsherr, wenn jedermann sein Bestes tut!
No doubt, my liege lord, if everyone does their best!
— Henry V (1989)
You have to do your best.
Manchmal reicht es nicht, sein Bestes zu geben.
Sometimes doing your best isn’t enough.
Everyone tries their best.
Man tut sein Bestes, sie richtig zu erziehen.
You do your best to raise them properly.
— Bullet Train (2022)
He did his best.
Tom tat sein Bestes.
Tom did his best.
He is doing his best.
Er wird schon sein Bestes geben.
He will do his best.
