sha.a.nan describes people or places portrayed as secure, sometimes in warnings against complacent self-assurance.

The adjective most often characterizes people or groups as secure, including contexts of warning, contempt, or judgment; it also describes a peaceful, settled dwelling-place or pasture.

1. Secure or complacent people and groups · dominant

   The adjective identifies those addressed as secure in Zion and Samaria in Amos 6:1, and feminine plural forms address secure women and those who trust in Isaiah 32:9 and Isaiah 32:11. In Job 12:5 and Zechariah 1:15, the APB places the secure or complacent persons within scenes of contempt and anger; the same adjective is therefore used of persons and groups whose security is exposed to rebuke or judgment.

2. A secure, settled place · occasional

   In Isaiah 32:18, the feminine plural adjective modifies dwellings in a picture of peace and quiet resting places. In Isaiah 33:20, the masculine singular form describes Zion as a pasture and a tent that will not be moved.

In the Anselm Project Bible: The APB uses “secure” in several clauses, but also has “arrogance” in 2 Kings 19:28, “security” in Isaiah 37:29, and “complacent” in Zechariah 1:15. These variations present the verse contexts rather than separate definitions of the adjective.
