Etymology

The name of Petach Tikva was chosen by its founders in 1878 from the prophecy of Hosea (2:17), "And I will give her vineyards from thence, and the Valley of Achor for an opening of hope: and she shall sing there, as in the days of her youth, and as in the day when she came up out of the land of Egypt."
Petach Tikva's emblem appears on a postage stamp designed by Yitzhak Goldenhirsch, a founding member of Petah Tikva. The plow symbolizes Petach Tikva's origins as an agricultural settlement, the field symbolizes the drying of the Yarkon River swamps and cultivation of the land, and the orange tree symbolizes Petach Tikva's citrus industry, starting with the first tree planted by Rabbi Arye Leib Frumkin.
