The Hebrew noun nowd means wandering, exile, or homelessness. It derives from the verb nuwd (H5110) meaning to wander or shake. The word carries the sense of restless, purposeless movement — the condition of one who has been uprooted from home and stability.
In the Psalms, nowd describes the psalmist's experience of suffering and displacement. The powerful image of God recording human tears in His bottle and wanderings in His book speaks to divine attentiveness to every moment of human suffering and exile. God does not overlook the restless pain of His people but keeps a faithful account of it all.
