'Willingness' in the Bible

You give me your protective shield; your willingness to help enables me to prevail.

They said to him, "Today if you show a willingness to help these people and grant their request, they will be your servants from this time forward."

Then the people rejoiced because of their leaders’ willingness to give, for they had given to the Lord with a whole heart. King David also rejoiced greatly.

You give me your protective shield; your right hand supports me; your willingness to help enables me to prevail.
