James 3:9

His mouth is full of cursing and deceit and fraud: under his tongue is mischief and vanity.

They only consult to cast him down from his excellency: they delight in lies: they bless with their mouth, but they curse inwardly. Selah.

Wherefore the Lord said, Forasmuch as this people draw near me with their mouth, and with their lips do honour me, but have removed their heart far from me, and their fear toward me is taught by the precept of men:

Whoso sheddeth man’s blood, by man shall his blood be shed: for in the image of God made he man.

For the sin of their mouth and the words of their lips let them even be taken in their pride: and for cursing and lying which they speak.

But Abishai the son of Zeruiah answered and said, Shall not Shimei be put to death for this, because he cursed the LORD’s anointed?

Therefore did my heart rejoice, and my tongue was glad; moreover also my flesh shall rest in hope:

This is the book of the generations of Adam. In the day that God created man, in the likeness of God made he him;

Therefore my heart is glad, and my glory rejoiceth: my flesh also shall rest in hope.

My tongue also shall talk of thy righteousness all the day long: for they are confounded, for they are brought unto shame, that seek my hurt.

Whose mouth is full of cursing and bitterness:

I will bless the LORD at all times: his praise shall continually be in my mouth.

And they went out into the fields, and gathered their vineyards, and trode the grapes, and made merry, and went into the house of their god, and did eat and drink, and cursed Abimelech.

Thus will I bless thee while I live: I will lift up my hands in thy name.

O God, my heart is fixed; I will sing and give praise, even with my glory.

And David said to all the congregation, Now bless the LORD your God. And all the congregation blessed the LORD God of their fathers, and bowed down their heads, and worshipped the LORD, and the king.

Awake up, my glory; awake, psaltery and harp: I myself will awake early.

But I say unto you, Love your enemies, bless them that curse you, do good to them that hate you, and pray for them which despitefully use you, and persecute you;

For oftentimes also thine own heart knoweth that thou thyself likewise hast cursed others.

Deliver me from bloodguiltiness, O God, thou God of my salvation: and my tongue shall sing aloud of thy righteousness.
