'Ought' in the Bible

"Let it be so on this occasion," Jesus replied; "for so we ought to fulfil every religious duty." Then he consented;

Therefore if thou bring thy gift to the altar, and there rememberest that thy brother hath ought against thee;

yet he has no [substantial] root in himself, but is only temporary, and when pressure or persecution comes because of the word, immediately he stumbles and falls away [abandoning the One who is the source of salvation].

ought not you also to have had pity on your fellow servant, just as I had pity on you?'

And if any man say ought unto you, ye shall say, The Lord hath need of them; and straightway he will send them.

Woe unto you, scribes and Pharisees, hypocrites! for ye pay tithe of mint and anise and cummin, and have omitted the weightier matters of the law, judgment, mercy, and faith: these ought ye to have done, and not to leave the other undone.

At that time many will be offended and repelled [by their association with Me] and will fall away [from the One whom they should trust] and will betray one another [handing over believers to their persecutors] and will hate one another.

Then you ought to have put my money in the bank, and on my arrival I would have received my money back with interest.
