Psalm 46/Notes/Phrasal.v. 6.525232

In the collocation at the approach of morning (לפנות בקר), literally, "in the turning of [or which is performed by] morning", the preposition ל is used temporally, appearing a number of times in constructions similar to לפנות בקר and signifying the “turn toward, approach, of some specific time." Of interest for Psalm 46 is that in HB, early morning is closely associated with warfare, both with the time of aggression and attacks (e.g., Josh 8:10-14; Jdg 9:33) and the time of deliverance (e.g., Exod 14:27-28; Isa 17:12–14; 29:5-7; 37:36; Ps 5:4; 30:5; 130:6).
