1 Samuel 18:7-9

Young's Literal Translation

⁷ and the women answer -- those playing, and say, `Saul hath smitten among his thousands, And David among his myriads.'

⁸ And it is displeasing to Saul exceedingly, and this thing is evil in his eyes, and he saith, `They have given to David myriads, and to me they have given the thousands, and more to him [is] only the kingdom;'

⁹ and Saul is eyeing David from that day and thenceforth.
