'Falsehood' in the Bible

Therefore, having laid aside falsehood, each one of you speak the truth with his neighbor, for we are members of one another.

but nothing ritually unclean will ever enter into it, nor anyone who does what is detestable or practices falsehood, but only those whose names are written in the Lamb's book of life.

Outside are the dogs and the sorcerers and the sexually immoral, and the murderers, and the idolaters and everyone who loves and practices falsehood!
