'Tender' in the Bible

'And there are gathered unto him vain men, sons of worthlessness, and they strengthen themselves against Rehoboam son of Solomon, and Rehoboam was a youth, and tender of heart, and hath not strengthened himself against them.

Because thy heart is tender, and thou art humbled before God in thy hearing His words concerning this place, and concerning its inhabitants, and art humbled before Me, and dost rend thy garments, and weep before Me: even I also have heard -- the affirmation of Jehovah.
