These passages are taken from the King James Version of the Bible to illustrate uses of parallel form. One could look to other sources in the Bible, of course. The Song of Solomon is filled with moments of extreme and beautiful lyricism. The King James Version probably does greater justice to the parallel rhythms of English than do later translations.

Matthew 5:3-11: The Beatitudes

Blessed are the poor in spirit: for theirs is the kingdom of heaven.
Blessed are they that mourn: for they shall be comforted.
Blessed are the meek: for they shall inherit the earth.
Blessed are they which do hunger and thirst after righteousness: for they shall be filled.
Blessed are the merciful: for they shall obtain mercy.
Blessed are the pure in heart: for they shall see God.
Blessed are the peacemakers: for they shall be called the children of God.
Blessed are they which are persecuted for righteousness' sake: for theirs is the kingdom of heaven.
Blessed are ye, when men shall revile you, and persecute you, and shall say all manner of evil against you falsely, for my sake.

Matthew 6:9-13: The Lord's Prayer

After this manner therefore pray ye: Our Father which art in heaven, Hallowed be thy name.
Thy kingdom come, Thy will be done in earth, as it is in heaven.
Give us this day our daily bread.
And forgive us our debts, as we forgive our debtors.
And lead us not into temptation, but deliver us from evil: For thine is the kingdom, and the power, and the glory, for ever. Amen.

Deuteronomy 5:6-21: The Ten Commandments

I am the LORD thy God, which brought thee out of the land of Egypt, from the house of bondage.
Thou shalt have none other gods before me.
Thou shalt not make thee any graven image, or any likeness of any thing that is in heaven above, or that is in the earth beneath, or that is in the waters beneath the earth:
Thou shalt not bow down thyself unto them, nor serve them: for I the LORD thy God am a jealous God, visiting the iniquity of the fathers upon the children unto the third and fourth generation of them that hate me,
And shewing mercy unto thousands of them that love me and keep my commandments.
Thou shalt not take the name of the LORD thy God in vain: for the LORD will not hold him guiltless that taketh his name in vain.
Keep the sabbath day to sanctify it, as the LORD thy God hath commanded thee.
Six days thou shalt labour, and do all thy work:
But the seventh day is the sabbath of the LORD thy God: in it thou shalt not do any work, thou, nor thy son, nor thy daughter, nor thy manservant, nor thy maidservant, nor thine ox, nor thine ass, nor any of thy cattle, nor thy stranger that is within thy gates; that thy manservant and thy maidservant may rest as well as thou.
And remember that thou wast a servant in the land of Egypt, and that the LORD thy God brought thee out thence through a mighty hand and by a stretched out arm: therefore the LORD thy God commanded thee to keep the sabbath day.
Honour thy father and thy mother, as the LORD thy God hath commanded thee; that thy days may be prolonged, and that it may go well with thee, in the land which the LORD thy God giveth thee.
Thou shalt not kill.
Neither shalt thou commit adultery.
Neither shalt thou steal.
Neither shalt thou bear false witness against thy neighbour.
Neither shalt thou desire thy neighbour's wife, neither shalt thou covet thy neighbour's house, his field, or his manservant, or his maidservant, his ox, or his ass, or any thing that is thy neighbour's.
