'Further' in the Bible

John gave [further] evidence [testifying officially for the record, with validity and relevance], saying, “I have seen the Spirit descending as a dove out of heaven, and He remained upon Him.

Jesus told him, "Whoever has bathed is entirely clean. He doesn't need to wash himself further, except for his feet. And you men are clean, though not all of you."

After offering this prayer Jesus went out with His disciples to a place on the further side of the Ravine of the Cedars, where there was a garden which He entered--Himself and His disciples.
