Psalm 101: I mercy will and judgment sing

1 I mercy will and judgment sing,
Lord, I will sing to thee.
2 With wisdom in a perfect way
shall my behaviour be.
O when in kindness unto me,
wilt thou be pleased to come?
I with a perfect heart will walk
within my house at home.

3 I will endure no wicked thing
before mine eyes to be;
I hate their work that turn aside,
it shall not cleave to me.
4 A stubborn and a froward heart
depart quite from me shall;
a person given to wickedness
I will not know at all.

5 I’ll cut him off that slandereth
his neighbour privily:
the haughty heart I will not bear,
nor him whose look is high.
6 I'll mark the faithful of the land
that they may dwell with me;
who walketh in a perfect way
to me shall servant be.

7 Who of deceit a worker is
in my house shall not dwell;
and in my presence shall he not
remain that lies doth tell.
8 Each morn the wicked of the land
shall be cut off by me;
to root out from God’s city all
that work iniquity.
