God had planned something better for us so that only together with us would they be made perfect. (NIV)

Because God had us in mind and had something better and greater in view for us, so that they [these heroes and heroines of faith] should not come to perfection apart from us [before we could join them]. (AMP)

God having provided some better thing for us, that they without us should not be made perfect. (KJV)

The world was not worthy of them. They wandered in deserts and mountains, and in caves and holes in the ground. (NIV)

[Men] of whom the world was not worthy--roaming over the desolate places and the mountains, and [living] in caves and caverns and holes of the earth. (AMP)

(Of whom the world was not worthy:) they wandered in deserts, and in mountains, and in dens and caves of the earth. (KJV)

Sometimes you were publicly exposed to insult and persecution; at other times you stood side by side with those who were so treated. (NIV)

Sometimes being yourselves a gazingstock, publicly exposed to insults and abuse and distress, and sometimes claiming fellowship and making common cause with others who were so treated. (AMP)

Partly, whilst ye were made a gazingstock both by reproaches and afflictions; and partly, whilst ye became companions of them that were so used. (KJV)
