'Beseech' in the Bible

Then Aaron said to Moses, Alas, my lord, I beseech thee, lay not this sin upon us, wherein we have been foolish, and have sinned!

And Moses cried to Jehovah, saying, O God, heal her, I beseech thee!

And now, I beseech thee, let the power of the Lord be great, according as thou hast spoken, saying,

Pardon, I beseech thee, the iniquity of this people according to the greatness of thy loving-kindness, and as thou hast forgiven this people, from Egypt even until now.
