tn This verb has been traditionally understood as “measure” (from מוּד, mud), but the immediately following context (vv. 6b–7) favors the meaning “shake” from מָוד (mavd; see HALOT555s.v.).
tnHeb “ancient ways [or, “doings”] are his.” The meaning of this line is unclear. Traditionally it has been translated, “his ways are eternal.” However, in this context (see vv. 3, 7) it is more likely that the line speaks of the Lord taking the same route as in the days of Moses and Deborah (see Deut 33:2; Judg 5:4). See J. J. M. Roberts, Nahum, Habakkuk, and Zephaniah (OTL), 154.
