According to Nehemiah, the people living nearby warned them many times that enemies were planning to attack them from every direction. This made everyone feel worried and they had to be ready to protect themselves and stay safe.
Nehemiah 4:12: And it came to pass, that when the Jews which dwelt by them came, they said unto us ten times, From all places whence ye shall return unto us [they will be upon you]. [From all...: or, That from all places ye must return to us]
Nehemiah 4:12 reflects a defensive stance against their enemies, while Luke 6:29 advocates for non-resistance and turning the other cheek.
Luke 6:29: And unto him that smiteth thee on the [one] cheek offer also the other; and him that taketh away thy cloke forbid not [to take thy] coat also.
