Hymns In 3/4 Time Signature?

Hello. I'm looking for any Hymns in 3/4 time signature? Something along the lines of Hubert Parry's "Jerusalem." I'm just finishing a composition, for voice and piano, and I have the melody and the structure, but I need to spice up the piano, so I'm looking for ideas. Nothing too loud, as the melody is fairly complex, so I feel I need a simpler piano harmony, in order to achieve good balance. Also, national anthems would work equally as well. A 3/4 example would be, "Jeszcze Polska nie Zginęła." If you want to make my life even easier, your welcome to explain how you would go about writing a piano section in this format.Thanks in advance.

To God Be the Glory is my favorite in 3/4. Great os Thy Faithfulness is also great. There's a whole bunch of other ones. Just crack open any ol' hymnbook.

Study Bach chorales to learn how to harmonise hymns for SATB. Better still, get a job as a church musician and play this music every Sunday.

Thank you Tokkemon and Siwi. I am going to start studying To God Be the Glory, Great os Thy Faithfulness (which were both very good), and try to find some Bach chorale works that I like.

Be Thou My Vision is in 3/4. I also agree on studying Bach chorales to learn how to harmonise chorales in 4-parts. You'll learn so much about part-writing and chord voicings

If you have a psalter or a hymnal near by you could look them up for sure.
