'Months' in the Bible

These six were born to him in Hebron, where he reigned for seven years and six months.

So the Ark of God remained in the care of Obed-edom's household for three months, and God blessed Obed-edom's household, along with everyone associated with it.

Either three years of famine, or three months of reversals as you are swept away by your enemies while the sword of your enemies overtakes you, or three days with the sword of the LORD, consisting of pestilence infecting the land, with the angel of the LORD wreaking destruction from border to border throughout all of Israel.' Decide right now what I am to answer to the one who sent me."
