Hebrews 4:6

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 ) .
