The thief binds up people (Mk 3:27-3:27)

“But no one can enter

A strong man’s house

And plunder

His property,

Without first tying up

The strong man.

Then indeed,

He may plunder

His house.”

 

ἀλλ’ οὐ δύναται οὐδεὶς εἰς τὴν οἰκίαν τοῦ ἰσχυροῦ εἰσελθὼν τὰ σκεύη αὐτοῦ διαρπάσαι, ἐὰν μὴ πρῶτον τὸν ἰσχυρὸν δήσῃ, καὶ τότε τὴν οἰκίαν αὐτοῦ διαρπάσει.

 

There is something similar to this in Luke, chapter 11:21-22, and Matthew, chapter 12:29.  Here there is a reference to a strong man, probably Satan, who was overcome by another strong man, probably Jesus.  The strong man must be tied up before anyone can plunder his house.  Jesus, via Mark, appeared to be giving advice on how to rob a house.  No one would go into the house of a strong man (ἀλλ’ οὐ δύναται οὐδεὶς εἰς τὴν οἰκίαν τοῦ ἰσχυροῦ) to plunder seize, snatch, or rob his property or goods (εἰσελθὼν τὰ σκεύη αὐτοῦ ἁρπάσαι) without first tying up the strong man (ἐὰν μὴ πρῶτον τὸν ἰσχυρόν δήσῃ).  Then you would indeed be able to plunder or totally rob his whole house (καὶ τότε τὴν οἰκίαν αὐτοῦ διαρπάσει).  Thus, Satan would have to be bound up before you could enter his house to rob him.
