John Wesley on Joshua 14:12

This mountain - That is, this mountainous country. He names the country rather than the cities, because the cities were given to the Levites, chap.21:11,13. Thou heardest - Didst understand, both by the reports of others, and by thy own observation. Hearing, the sense by which we get knowledge, is often put for knowing or understanding. If the Lord will be with me - A modest and pious expression, signifying both the absolute necessity of God's help, and his godly fear, lest God for his sins should deny his assistance to him; for although he was well assured in general, that God would crown his people with success in this war, yet he might doubt of his particular success in this or that enterprize. To drive them out - Out of their fastnesses where they yet remain, Caleb desires this difficult work as a testimony of his own faith, and as a motive to quicken his brethren to the like attempts.
