'Mayest' in the Bible

This charge I commit to thee, child Timotheus, according to the prophesies that went before upon thee, that thou mayest war in them the good warfare,

and if I delay, that thou mayest know how it behoveth thee to conduct thyself in the house of God, which is an assembly of the living God -- a pillar and foundation of the truth,

An aged person thou mayest not rebuke, but be entreating as a father; younger persons as brethren;

I testify fully, before God and the Lord Jesus Christ, and the choice messengers, that these things thou mayest keep, without forejudging, doing nothing by partiality.
