Комментарий к Шмуэль А 20:20

I will shoot in that direction. This is not a dotted ה׳. Thus צִדָּה is interpreted like לַצַּד [to a side].²⁰Radak explains צִדָּה as if it had a ׳מַפִּיק ה׳ meaning ‘to its side, i.e., the side of the stone’ he will shoot the arrow. Every word which requires a 'ל' as a prefix, Scripture puts a 'ה' as a suffix,²¹Maseches Yevamos 13b. meaning, 'at the side of that stone, I will shoot arrows to a target' so that the youth will not understand, and this sign will be for you to divine whether you need to run away.
