Listen, look, but keep silent.
Literal
Listen, look, but be-silent.
Uses three imperative forms: 聞け (godan imperative of 聞く), 見よ (classical imperative of 見る — the modern form would be 見ろ), and 黙っていよ (imperative of 黙っている). 見よ gives this an archaic, proverbial flavor. The structure is a three-part command linked by しかし (but).
