In Matthew 18:18 (KJV), Jesus says, "Verily I say unto you, 'Whatsoever ye shall bind on earth shall be bound in heaven: and whatsoever ye shall loose on earth shall be loosed in heaven.'"
In Strong's Concordance, the word "bind" is G1210 – deō. "Deo" means, "to bind tie, fasten; fasten with chains, to throw into chains; put under obligation, of the law, duty etc., to be bound to one, a wife, a husband; to forbid, prohibit, declare to be illicit."
The definition also states: "Satan is said to bind a woman bent together by means of a demon, as his messenger, taking possession of the woman and preventing her from standing upright." We'll come back to this reference to Luke 13:12 in a moment, but for now, it should be clear that when we're praying according to Matthew 18:18, we would want to avoid declaring a person to be chained to or put under obligation of demons.
Let's look at some other scripture references. "Binding" is also mentioned in Matthew 12:29 and Matthew 16:19.
Matthew 12:29 (KJV) does indicate that we should bind the strongman. "Or else how can one enter into a strong man's house, and spoil his goods, except he first bind [G1210] the strong man? and then he will spoil his house."
Matthew 16:19 (KJV) also says, "And I will give unto thee the keys of the kingdom of heaven: and whatsoever thou shalt bind [G1210] on earth shall be bound [G1210] in heaven: and whatsoever thou shalt loose on earth shall be loosed in heaven."
Compare Matthew 18:18 (AMPC) with our original KJV verse: "Truly I tell you, whatever you forbid and declare to be improper and unlawful on earth must be what is already forbidden in heaven, and whatever you permit and declare proper and lawful on earth must be what is already permitted in heaven."

Rather than "binding" a person to a spirit of infirmity (for example), we would want to "loose" them from it, wouldn't we?
"Loose" is defined in Strong's Concordance as G3089 (lyō), meaning, "to loose any person (or thing) tied or fastened; bandages of the feet, the shoes; of a husband and wife joined together by the bond of matrimony; of a single man, whether he has already had a wife or has not yet married; to loose one bound, i.e. to unbind, release from bonds, set free; of one bound up (swathed in bandages); bound with chains (a prisoner), discharge from prison, let go; to loosen, undo, dissolve, anything bound, tied, or compacted together; an assembly, i.e. to dismiss, break up; laws, as having a binding force, are likened to bonds; to annul, subvert; to do away with, to deprive of authority, whether by precept or act; to declare unlawful; to loose what is compacted or built together, to break up, demolish, destroy; to dissolve something coherent into parts, to destroy, to overthrow, to do away with."
You need not find this confusing. We find clarity as we look to Jesus' example in Luke 13:12 (AMPC), "And when Jesus saw her, He called [her to Him] and said to her, Woman, you are released from your infirmity!"
All commands are in Jesus' Name according to John 14:13-14. Sticking with the previous example, it can be as easy as declaring, "In Jesus' Name, I release you from your infirmity" or "I release you from the bondage of fear."
