24 So David hid himself in the field: and when the new moon was come, the king sat him down to eat food. 25 And the king sat upon his seat, as at other times, even upon the seat by the wall; and Jonathan stood up, and Abner sat by Saul's side: but David's place was empty. 26 Nevertheless Saul spake not anything that day: for he thought, Something hath befallen him, he is not clean; surely he is not clean. 27 And it came to pass on the morrow after the new moon, [which was] the second [day], that David's place was empty: and Saul said unto Jonathan his son, Wherefore cometh not the son of Jesse to meat, neither yesterday, nor to-day? 28 And Jonathan answered Saul, David earnestly asked leave of me to go to Beth-lehem: 29 and he said, Let me go, I pray thee; for our family hath a sacrifice in the city; and my brother, he hath commanded me [to be there]: and now, if I have found favor in thine eyes, let me get away, I pray thee, and see my brethren. Therefore he is not come unto the king's table. 30 Then Saul's anger was kindled against Jonathan, and he said unto him, Thou son of a perverse rebellious woman, do not I know that thou hast chosen the son of Jesse to thine own shame, and unto the shame of thy mother's nakedness? 31 For as long as the son of Jesse liveth upon the ground, thou shalt not be established, nor thy kingdom. Wherefore now send and fetch him unto me, for he shall surely die. 32 And Jonathan answered Saul his father, and said unto him, Wherefore should he be put to death? what hath he done? 33 And Saul cast his spear at him to smite him; whereby Jonathan knew that is was determined of his father to put David to death. 34 So Jonathan arose from the table in fierce anger, and did eat no food the second day of the month; for he was grieved for David, because his father had done him shame.

Commentary on 1 Samuel 20:24-34

(Read 1 Samuel 20:24-34)

None were more constant than David in attending holy duties; nor had he been absent, but self-preservation obliged him to withdraw. In great peril present opportunities for Divine ordinances may be waved. But it is bad for us, except in case of necessity, to omit any opportunity of statedly attending on them. Jonathan did wisely and well for himself and family, to secure an interest in David, yet for this he is blamed. It is good to take God's people for our people. It will prove to our advantage at last, however it may now be thought against our interest. Saul was outrageous. What savage beasts, and worse, does anger make men!
