'Precisely' in the Bible

Then Herod secretly summoned the wise men [and] determined precisely from them the time [when] the star appeared.

Then Herod, [when he] saw that he had been deceived by the wise men, became very angry, and he sent [soldiers] [and] executed all the children in Bethlehem and in all the region [around] it from [the age of] two years old and under, according to the time which he had determined precisely from the wise men.
