Seeing therefore it remaineth
 It follows by just consequence, 
 that some must enter therein;
 for God's swearing concerning some, that they should not enter into his rest, supposes that others should: and 
 they to whom it was first preached;
 to whom the Gospel was first preached, namely, the Israelites in the wilderness: entered not in because of unbelief; See ( Hebrews 3:19 ) .
