Passage
For thy word`s sake, and according to thine own heart, hast thou wrought all this greatness, to make thy servant know it.
For thy word`s sake, and according to thine own heart, hast thou wrought all this greatness, to make thy servant know it.
2 Samuel 7:19 And this was yet a small thing in thine eyes, O Lord Jehovah; but thou hast spoken also of thy servant`s house for a great while to come; and this [too] after the manner of men, O Lord Jehovah!
2 Samuel 7:20 And what can David say more unto thee? for thou knowest thy servant, O Lord Jehovah.
2 Samuel 7:21 For thy word`s sake, and according to thine own heart, hast thou wrought all this greatness, to make thy servant know it.
2 Samuel 7:22 Wherefore thou art great, O Jehovah God: for there is none like thee, neither is there any God besides thee, according to all that we have heard with our ears.
2 Samuel 7:23 And what one nation in the earth is like thy people, even like Israel, whom God went to redeem unto himself for a people, and to make him a name, and to do great things for you, and terrible things for thy land, before thy people, whom thou redeemest to thee out of Egypt, [from] the nations and their gods?
The verse centers on "word", "sake", "thine", "heart", "hast", "thou", "wrought", and "greatness". It is saying that the verse draws attention to "word" and "sake", so its meaning should be read from those terms before moving to application.
The nearby context moves from verse 20's "And what can David say more unto..." into verse 22's "Wherefore thou art great O Jehovah God...", so "word" and "sake" belong inside that flow. In 2 Samuel context, the local focus is covenant, worship, and faithfulness.
A plain takeaway is to answer the verse's own emphasis on "word" and "sake" with trust shaped by these words, not by a vague optimism outside the passage.
