Concise Bible Dictionary:

The word is from ἐντυγχάνω, which signifies “to meet with, to intercede.” It refers to the intercession of Christ for His saints, while in their present state, to bring them into conformity with the place justifying forgiveness has given them, also to raise them above their trials, and lead them on as priests into the blessed joys and occupations of the sanctuary (Rom. 8:34; Heb. 7:25). The Holy Spirit also, when they know not what to pray for as they ought, makes intercession for the saints with groanings which cannot be uttered (Rom. 8:26-27). In 1 Timothy 2:1 we are instructed to make intercession for all men. It is remarkable that a substantive (ἔντευξις) formed from the above verb is used in 1 Timothy 4:5, where food is sanctified by the word of God and “prayer,” or, as it there means, reverent communication with Him.

 Full of love to them as the people of God, their rejection of himself does not for a moment suggest the thought to him of giving up his intercession or his testimony for their welfare. Beautiful picture of a heart near the Lord, which, in forgetfulness of self, can love His people as its own! (1 Samuel 12 by J.N. Darby)
