שָׁלַשׁ

From LSJ

Γυνὴ δὲ χρηστὴ πηδάλιόν ἐστ' οἰκίας → Honesta mulier est gubernaculum domus → Des Hauses Steuerruder ist die brave Frau

Menander, Monostichoi, 99

English (Strong)

a primitive root perhaps originally to intensify, i.e. treble; but apparently used only as denominative from שָׁלוֹשׁ, to be (causatively, make) triplicate (by restoration, in portions, strands, days or years): do the third time, (divide into, stay) three (days, - fold, parts, years old).
