Maher (II) functions as an adverb meaning 'quickly' or 'speedily,' derived from the Piel infinitive absolute of mahar ('to hasten'). Its 17 occurrences always follow directly after the verb they modify, lending urgency to the action described. The word appears most densely in Deuteronomy, where it underscores both the swiftness of divine judgment — 'you shall surely perish quickly from the land' (Deut 4:26; 28:20) — and the pace of God's warfare on Israel's behalf: 'He will destroy them quickly before you' (Deut 9:3). The golden calf narrative uses it twice: 'they have turned aside quickly from the way I commanded them' (Deut 9:12, 16; cf. Exod 32:8), conveying the shocking speed of Israel's apostasy. In Judges 2:17, 23, it describes how quickly Israel abandoned the Lord after Joshua's generation died. Joshua 2:5 records Rahab's cover story about the spies: 'pursue them quickly.' Proverbs 25:8 warns against rushing too quickly into a legal dispute. The name Maher-shalal-hash-baz (Isa 8:1) builds on this same root. Spanish 'rapidamente,' French 'rapidement,' and German 'schnell' all render the straightforward adverbial sense.
