'Maintain' in the Bible

I maintain a pure lifestyle, so I can appear before your altar, O Lord,

Trust in the Lord and do what is right! Settle in the land and maintain your integrity!

As for me, you will maintain my just cause, and you will cause me to stand in your presence forever.

Even the stock which Your right hand has planted,And [look down on] the son that You have reared and strengthened for Yourself.

Vindicate the weak and fatherless;Do justice and maintain the rights of the afflicted and destitute.

He who practices deceit shall not dwell within my house;He who speaks falsehood shall not maintain his position before me.

He does not maintain a dispute continuously or remain angry for all time.

It is well with the man who is gracious and lends;He will maintain his cause in judgment.

(Bet) How can a young person maintain a pure life? By guarding it according to your instructions!

I know that the LORD will maintain the cause of the afflicted, and the right of the poor.
