A certain scribe - Though ἑις γραμματευς, One scribe, may be considered as a Hebraism, yet it is probable that the literal construction of it was intended, to show that few of this class came to the Lord Jesus for instruction or salvation.

Master - Rather, teacher, διδασκαλε from διδασκω, I teach, which itself seems to be derived from δεικω, I show, and means the person who shows or points out a particular way or science.

I will follow thee whithersoever thou goest - A man who is not illuminated by the Spirit of God thinks himself capable of any thing: he alone who is divinely taught knows he can do nothing but through Christ strengthening him. Every teacher among the Jews had disciples, and some especially that followed or accompanied them wherever they went, that they might have some person at hand with whom they might converse concerning the Divine law.

Christ Repressing Rash Discipleship
'And a certain scribe came, and said unto Him, Master, I will follow Thee whithersoever Thou goest. 20. And Jesus saith unto him, The foxes have holes, and the birds of the air have nests; but the Son of Man hath not where to lay His head.'--MATT. viii. 19-20. Our Lord was just on the point of leaving Capernaum for the other side of the lake.

Heaven and Hell
To-night, I shall, I hope, encourage you to seek the road to heaven. I shall also have to utter some very sharp things concerning the end of the lost in the pit of hell. Upon both these subjects I will try and speak, as God helps me. But, I beseech you, as you love your souls, weigh right and wrong this night; see whether what I say be the truth of God.

We find, on one touching …
