'Began' in the Bible

Saul was [thirty] years old when he began to reign; he ruled over Israel for [forty] years.

He waited for seven days, the time period indicated by Samuel. But Samuel did not come to Gilgal, and the army began to abandon Saul.

Was it just today that I began to inquire of God on his behalf? Far be it from me! The king should not accuse his servant or any of my father's house. For your servant is not aware of all this -- not in whole or in part!"
