'Earnestly' in the Bible

She made a vow, saying, “O Lord of hosts, if You will indeed look on the affliction (suffering) of Your maidservant and remember, and not forget Your maidservant, but will give Your maidservant a son, then I will give him to the Lord all the days of his life; a razor shall never touch his head.”

If your father misses me at all, then say, ‘David earnestly asked permission from me to go to Bethlehem, his city, because it is the yearly sacrifice there for the entire family.’

Jonathan answered Saul, “David earnestly asked me for permission to go to Bethlehem.

that this [incident] will not cause grief or [bring] a troubled conscience to my lord, both by having shed blood without cause and by my lord having avenged himself. When the Lord deals well with my lord, then remember [with favor] your maidservant.”
