But know this, that if the head of the house had known in what watch of the nighta the thief was coming, he would have watched, and would not have allowed the wall of his house to be dug through. Bible other translations
In NT times, the day was divided into 12 hours (John 11:9) and the night into 4 watches: 1st: 6-9 PM; 2nd: 9 PM -midnight; 3rd: midnight -3 AM; 4th: 3-6 AM (Mark 13:35).

“allowed” = eao (#1439) = “1. to let, allow, permit; 2. to let alone, to allow to do as one wishes; 3. to let go, give up, leave.” The difference between “let,” “allow,” and “permit” can be very slight, but “allow” usually means no more than lack of prohibition whereas “permit” implies a granting of express permission. Thus “allow” was usually the better choice for eao in this verse.

“dug through.” Biblical custom. Most houses were of some mud or mud and stone construction, so thieves “dug through” the wall and gained entrance to the house.
