'Whether' in the Bible

The people watched Jesus closely to see whether he would heal him on the Sabbath, intending to accuse him of doing something wrong.

Wherever he went, whether into villages, towns, or farms, people would place their sick in the marketplaces and beg him to let them touch even the tassel of his garment, and everyone who touched it was healed.

So keep on watching, because you don't know when the master of the house is coming whether in the evening, at three o'clock in the morning, or at dawn.
