Mark 12:35-37 and 2 Timothy 3:10-17

Mark 12:35-37
35 And while teaching in the temple, Jesus said in answer: "How is it that the scribes say that the Christ is the son of David?
36 For David himself said in the Holy Spirit: 'The Lord said to my Lord: Sit at my right hand, until I set your enemies as your footstool.'
37 Therefore, David himself calls him Lord, and so how can he be his son?" And a great multitude listened to him willingly.
2 Timothy 3:10-17
10 But you have fully comprehended my doctrine, instruction, purpose, faith, longsuffering, love, patience,
11 persecutions, afflictions; such things as happened to me at Antioch, at Iconium, and at Lystra; how I endured persecutions, and how the Lord rescued me from everything.
12 And all those who willingly live the piety in Christ Jesus will suffer persecution.
13 But evil men and deceivers will advance in evil, erring and sending into error.
14 Yet truly, you should remain in those things which you have learned and which have been entrusted to you. For you know from whom you have learned them.
15 And, from your infancy, you have known the Sacred Scriptures, which are able to instruct you toward salvation, through the faith which is in Christ Jesus.
16 All Scripture, having been divinely inspired, is useful for teaching, for reproof, for correction, and for instruction in justice,
17 so that the man of God may be perfect, having been trained for every good work.
