'Humbly' in the Bible

Then said the king to Ziba, Behold, thine are all that pertained unto Mephibosheth. And Ziba said, I humbly beseech thee that I may find grace in thy sight, my lord, O king.

He hath shewed thee, O man, what is good; and what doth the LORD require of thee, but to do justly, and to love mercy, and to walk humbly with thy God?
