| Gill's Exposition of the Entire Bible And Saul cast a javelin at him to smite him,.... So provoked to wrath was he by what he said. It seems by this that Saul always had a javelin or spear in his hand, which is to be accounted for by the custom of those times; in other countries, as well as in this, the kings used to carry spears in their hands instead of sceptres, and which they used as such; so Justin (h), speaking of the times of Romulus, says, that kings in those times had spears, as an ensign of royalty, which the Greeks call sceptres; and so the Greeks called sceptres spears (i): whereby Jonathan knew that it was determined of his father to slay David; for since he attempted to smite him, his own son, for speaking on his behalf, it might be well concluded, that such was his settled wrath and malice, that he would if possible kill David, could he get him into his hands.

Wesley's Notes 20:33 To smite him - Saul seemed to be in great care, that Jonathan should be established in his kingdom: and now he himself aims at his life! What fools, what worse than savage beasts does anger make.
Jamieson-Fausset-Brown Bible Commentary33. Saul cast a javelin at him-This is a sad proof of the maniacal frenzy into which the unhappy monarch was transported.
Matthew Henry's Concise Commentary20:24-34 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! |
