'Relentlessly' in the Bible

may an enemy relentlessly chase me and catch me; may he trample me to death and leave me lying dishonored in the dust. (Selah)

When I tripped, they taunted me relentlessly, and tried to bite me.

This is what the Lord says: "Because Edom has committed three crimes -- make that four! -- I will not revoke my decree of judgment. He chased his brother with a sword; he wiped out his allies. In his anger he tore them apart without stopping to rest; in his fury he relentlessly attacked them.
