19 because what can be known about God is plain to them, because God has made it plain to them.

Darby

19 Because what is^D7969 known of God is manifest among them, for God has manifested [it] to them,

Darby Bible Notes

is - Or 'may be.' The Greek word here is used for 'may be known.' What is spoken of here is 'knowledge acquirable by nature in contrast with revelation,' it means what is within the capacity of man's apprehension. But 'is known' sufficiently represents that and is more exact.

KJV

19 Because that which may be known of God is manifest in them^K6802; for God hath shewed [it] unto them.

KJV Bible Notes

in them: Or, to them.
