strait and narrow

The phrase "strait and narrow" is a biblical reference commonly used in English language idioms to describe the path of righteousness or moral rectitude. It is derived from the Bible verse Matthew 7:14, which states, "Because strait is the gate, and narrow is the way, which leadeth unto life, and few there be that find it." In this context, "strait" and "narrow" refer to the difficulties and challenges faced when following a righteous or virtuous path, which is often considered to be a narrow and restrictive one. Hence, the phrase "strait and narrow" is used to convey the idea of staying on the right track, following moral guidelines, and avoiding temptation or sin.
