אֲדֹנָי ׀ שְׁמָעָה אֲדֹנָי ׀ סְלָחָה אֲדֹנָי הַֽקֲשִׁיבָה וַעֲשֵׂה אַל־תְּאַחַר לְמַֽעֲנְךָ אֱלֹהַי כִּֽי־שִׁמְךָ נִקְרָא עַל־עִירְךָ וְעַל־עַמֶּֽךָ׃
In the ESV, this is:
"O Lord, hear; O Lord, forgive. O Lord, pay attention and act. Delay not, for your own sake, O my God, because your city and your people are called by your name."
There are three vocatives referring to God in roughly the first half of the verse ("'O Lord, hear; O Lord, forgive. O Lord, pay attention and act.'"), and these are paralleled with a single vocative in the second half ("'Delay not, for your own sake, O my God, because your city and your people are called by your name.'"). To some degree, the placement of these vocatives indicates the Trinity: three Persons but one God.
