Psalms 6:2

The king then expressed his request positively. He begged for relief from his extreme discomfort. David spoke of his bones as representing his whole body (cf. Psalms 31:10; Psalms 32:3; Psalms 38:3; Psalms 42:10; Psalms 102:3; Psalms 102:5). This is a figure of speech called synecdoche in which the writer uses a prominent part in place of the whole.
