'On Earth' in the Bible

Were he on earth, he would not be a priest at all, for there are priests already to offer the gifts prescribed by Law

(These all died in faith without obtaining the promises; they only saw them far away and hailed them, owning they were 'strangers and exiles upon earth.'

See that you do not refuse to listen to His voice. For if they failed to escape, who refused to listen to their instructor upon earth, much less shall we escape, if we discard Him who speaks from heaven.
