'Willingly' in the Bible

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.
