cross-currents two currents which meet in a body of water Other scholars, however, interpret διθάλασσος together with τόπος as being a reef, a sandbar, or even a headland (see 1.68).
Cross-currents may be spoken of as ‘streams in the sea’ or ‘rivers in the sea’ or ‘two rivers that meet in the sea.’ It would be wrong, however, to use the expression ‘two rivers that meet in the sea’ if this meant merely two rivers which meet at the coastline as they flow from the interior. In this context ‘rivers’ can only refer to ‘rivers of the sea,’ in other words, ‘currents.’

Collocation: τόπος διθάλασσος
sandbar, reef a bar or reef produced in an area where two currents meet It is possible to understand τόπος διθάλασσος in ACT 27:41 as a place of crosscurrents; see 14.32. In some languages it may be necessary to construct a descriptive equivalent for ‘sandbank,’ for example, ‘a hill of sand just beneath the surface of the water’ or ‘a ridge of sand hidden by the water.’
