'Willingly' in the Bible

All Judah was happy about the oath, because they made the vow with their whole heart. They willingly sought the Lord and he responded to them. He made them secure on every side.

And next him was Amasiah the son of Zichri, who willingly offered himself unto the LORD; and with him two hundred thousand mighty men of valour.

And his princes gave willingly unto the people, to the priests, and to the Levites: Hilkiah and Zechariah and Jehiel, rulers of the house of God, gave unto the priests for the passover offerings two thousand and six hundred small cattle, and three hundred oxen.
