'Whether' in the Bible

The scribes and the Pharisees were watching Jesus closely to see whether he would heal on the Sabbath, in order to find a way of accusing him of doing something wrong.

"Suppose one of you wants to build a tower. He will first sit down and estimate the cost to see whether he has enough money to finish it, won't he?

"Or suppose a king is going to war against another king. He will first sit down and consider whether with 10,000 men he can fight the one coming against him with 20,000 men, won't he?

When Pilate heard this, he asked whether the man was a Galilean.
