'Persistent' in the Bible

then Jehovah will make thy plagues wonderful, and the plagues of thy seed, great and persistent plagues and evil and persistent sicknesses;

His anger tears me in his persistent resentment against me; he gnashes his teeth at me. My adversary glares at me.

She seduces him with her persistent pleading;she lures with her flattering talk.

Plans of the persistent surely lead to productivity, but all who are hasty will surely become poor.
